Earthquake Engineering

Earthquake Engineering

Earthquake Engineering

(OP)
Hello everyone

I have a graduate degree in Civil Engineering emphasising Structural Engineering.  I am thinking of taking Earthquake engineering as a course, does it make sense to take a course like this or should I save my money and learn it on my own.  I saw one time a posting for a job that required an engineer to have a graduate course in earthquake engineering and if I do not have to take it in terms that not taking one course will not hold me back as a structural engineering, then I will skip it.


Thanks

RE: Earthquake Engineering

Seismic engineering requirements are becoming more prevalent in all codes. It is simply a matter of degree and and determining whether it is critical for the particular structure.

Since you never know where you will be practicing, take the course and develop a basic understanding of the concepts and applicability to current codes. The newer codes may require more seismic analysis, so it is not not time wasted.

I was just speaking to a colleage and he was saying that the codes are not based that I have a full understanding of earthquake but that I can apply  the building code.  In addition, he mentioned that employers that may want to hire someone who with a earthquake engineering background, do not simple look at someone that took one  course but someone that took earthquake as well as base isolation and other courses as well as the experience to design dampeners or devices for a bridge or building.  Which requires more than one course and alot of time in study.  If that is the case, it may be just worth it for me just to learn it on my own.

Take it.  It will help you get an SE license (IL, CA, WA come to mind) in the future.

Cant you learn earthquake on your own and take the SE license as well?

RE: Earthquake Engineering

I'd say that it really depends on the course.  

I'd say that, for the most part, what you want to become familiar with are the the seismic loading codes (ASCE-7) and the seismic detailing provisions of AISC and ACI and how to apply them. That can be more complex than it sounds...especially for engineers who didn't cut their teeth doing design in California to the UBC.  

Now, the guys who do base isolation and mass dampers and such are usually specialists.  They probably work for the larger and more prestigious engineering companies that specializes in high end seismic design.... great work if you can get it.  But, the vast majority of engineering work here in the US (even here in California) would not require that type of expertise.   

RE: Earthquake Engineering

(OP)
I am not really interested in the expertise per se.  I just do not want to be limited in terms of career oppurtunities or a job for that matter, because I did not take a course.  I worked hard to get where I am and it is frustrating seeing doors closing in front in me because I do not have this or that.  I just want to get a feel if this is something I should do because of advantages or should I just read a book on Earthquake Engineering and learn on my own.

RE: Earthquake Engineering

Calif,
I cannot help out in your exact situation (I'm in Florida, no shakey ground here). Though I believe there is no substitute for on the job training, there are some economic realities to deal with these days. Employers who would hire just about anyone with a BSCE 5 or 10 years ago can now demand Masters Degrees and specialized coursework. If you have the time and there is a college nearby, any continuing education in your field won't HURT you. Its been 13 years since I got my BS and I am considering going back one class at a time to keep my options open down the road.

RE: Earthquake Engineering

No offense intended here, but unless you can explain here in a treatise what an Eigenvalue and an Eigenvector is, and their specific use in seismic engineeering, take the course.

In low rise buildings, it will probably not help you with the design, and applying the code would be paramount as your professor mentioned.  However, with high-rise structures, I have to disagree with him.  Many of these are cutting edge, and the code is only a small part.  These structures frequently rewrite sections of the code, whether they fail or not.  (bigsmile)

So, ask yourself...  What do you want to do?  (ponder)

RE: Earthquake Engineering

if you love bread and amazed on how those things puff like that, then be a baker.

I can say that if you are really interested on that field then go with It.... But experience is the best teacher, I suggest you must find a firm who do specialized on that field (they are mostly big and prestigious companies)so that you will expose yourself much on it. And if you think you really want that field then get a Masters with that specialty

RE: Earthquake Engineering

Jump for any education you can get whether it is formal of employment experience. Your direction may change, but no one can eliminate the experience.

Coming out of college as an EIT, it took a facilities engineering job for about 2 years in the aerospace industry. My fist design failed when an unexpected cloud/bubble of hydrogen gas exploded over the the building an caused loads that were beyond any code or standard, but I learned that situations require different thinking. The roof was rebuilt in a week and all computers were replaced and the cleaning and venting process was changed to recognize the possibilities.

While still an EIT, I has a registered California structural engineer working for me doing dynamic analysis (learn as you go)on rocket test stands (similar natural frequency to 20 story high rise steel structures) where the structural dynamics, put the loads went up because the vibrating, gimballing engine was firing and the 200,000# of fuel was burned off. Fortunately because of the company resources and structural failures of an acceptance test stand, we had program where we were able it place meters at every joints for acceleration and down load the results into a sister company's airframe program (North American Aviation) to determine the actual loads. With this we compared it to the current (at the time) stresses and deflections as a guide for future designs - the right place at the right time.

Four years later after getting in2 years of direct construction experience, I worked for a utility and was involved is the site analysis for a nuclear plant where we needed a soil consultant to place measuring eauipment and set off charges to determine the characteristics of the site and the effect of the high water table in an alluvial soil. At the day of the the testing, the engineer from the soil consultant (Dames & Moore?) turned out to be my supervisor on rocket test stand design and analysis.

My direction has changed and I have been involved in code and construction internationally (40 countries) and found a home.

The bottom line is to take advantage of everything you can do to broaden your experience since you have many years to go and many options in addition to those you see now.

RE: Earthquake Engineering

Take the course especially if it requires one to have already taken structural dynamics such that the earthquake engineering course can cover more information about seismicity, developement of RSA elastic and inelastic, mass dampers, and all the materials such as steel, concrete, masonry and their seismic detailing requirements.  

If the course description says that it will cover SDOF and MDOF systems along with the IBC code then you can figure on spending 90% of your time in structural dynamics and 10% on the code if there is time.

I've taken structural dynamics and earthquake engineering courses.  Structural dynamics was necessarily theoretical and useful but the course on earthquake engineering really built on that knowledge not rehashed it.

RE: Earthquake Engineering

Oh, and IMHO, you cannot learn earthquake engineering on your own, ie, through experience.  The reason is that earthquake engineering covers many, many topics that you're business may not work in.  But having the coursework will give you insight into those areas so you can pick up where the professor left off and work more on your own.

RE: Earthquake Engineering

(OP)
Hi Qshake,

My office includes earthquake in design but nobody really analysis models for earthquake forces.  So if I wanted to learn how programs come up with earthquake forces, I pretty much will have to do it on my own.  I work for a small place but bigger firms may have more concern of analyzing models and more QC and understanding may be needed.

Concrete Masonry

I am glad you replied to that, it gets me thinking that I may need that flexibility that you have in your experience. As mentioned before, I have been shut out due to opportunity because I did not have something or not enough experience but now it gets me thinking that we do not know what the future may bring but  having flexibility gives me more options.

Msquare,

I am going to ponder it more.  I have never done a sky scraper and do not see myself really wanting to do one.  In fact, if I get to do a hospital or office building, I would be happy doing something like that or a low rise building that is big area but not really high at all.  I am just not fascinated by tall structures but things that look good and well design and close to the ground.  Maybe a stadium one day but not sky scrapers.

I hear what you are saying, and I like to keep my options open but I will say this, man, I am tired of going to night class and being pinned to a schedule with no life.  Really do not feel like studying unless it is worth the time.

Joshplum

If I understand your reasoning, it leads me to think that any engineer who intends not to specialize in earthquake engineering requiring designing dampening systems and base isolation analysis, needs no course in earthquake engineering.   They only need to apply the codes for ASCE-7 and seismic requirement for detailing.  Am I wrong in what you mean?

RE: Earthquake Engineering

I don't know about the course you are considering, but I expect that such courses teach more than just determining forces. Seismic design is not a complicated methodology created for just coming up with some force values to load your structure with - after all there are simplified methods that can give you a fare estimate of the forces without "precise" 3D modelling - noone can ever know what the _exact_ forces will be.

They should teach you the difference of brittle versus ductile behaviour, how to design and detail the joints and elements of the structure so they can dissipate energy. They will tell you how soil conditions affect the impact the earthquake will have on the structure, how different foundation systems should be designed in order to work as modelled, and many, many other things.

Even if you have good references, it is worth taking a course - it will not teach you only the material you expect - points from the agenda - you will meet experienced people, you will be told things from the practice of the lecturer that are not in the books. And more important - you will be given the chance to ask questions - either to the lecturer or the other participants in the coffee break - things you can't do when simply reading a book. It is a professional meeting with educational purpose, not just a lecture that costs M dollars and will pay you back N dollars in the future.

And as you are concerned about the career - you can meet yout next employer there or meet people who work for him and that can tell you about their work.

RE: Earthquake Engineering

As Mikesq said, do as much as you can to get exposure to different areas and make contacts.

When I worked in facilities engineering in the aerospace industry, we were required to have continuing education to beef up the credentials and resume for the purposes of getting additional contracts. The upside was they paid the tuition plus any travel and time (overtime) because many classes for a Masters were offered at night. I took evening classes at USC and obviously the instructors were from private practice area and had practical experience. I learned more about structures (dynamic and seismic) in one class that put everything together and in perspective relative to the real world. - Six months later our company hired a firm (Parsons?) on some seismic and dynamic analysis and and the lead man from the firm was my instructor at USC. It made it easy to understand and work with the firm on a project and we were only 5 or 10 years apart and enjoyed a few beers in barren places for casual meetings around the Edwards AFB where the NASA acceptance rocket test stands were.

The more you move around and get exposure, the more you learn from both an academic and practical standpoint.

RE: Earthquake Engineering

Calif -

That's not really what I meant.

I actually meant that there are many different topics that can be covered in an earthquake engineering course.  If your course is mostly related to very specialized topics (base isolation and damping systems) then it may not be worth it unless this is the area you want to specialize in. Universities will sometimes focus their course work on more academic topics that interest the professors, but which may not be particularly relevant to practicing engineers.  

However, if the course covers more pratical earthquake engineering then it would be worth taking. By more practical, I would be referring to topics more commonly used or needed during the normal design practice of a structural engineer.  This would included: General seismicity, response spectra analysis, steel and concrete detailing to resist seisic loads.... even push over analysis.

You asked "Besides designing support for buildings and bridges, what else can a structural engineer do?"

Structurally speaking, a licensed Structural Engineer is like an elephant.  He (or she) does anything he wants (and feels comfortable doing).

I think I understand what you are talking about.  The course I think will be more academic and not practical to be honest but I do not know.  I have never taken this professor before but I guess, I could ask.  I am sure it will go over response spectrum and such but ASCE-7 codes or connections for seismic design, I doubt.

RE: Earthquake Engineering

"Besides designing support for buildings and bridges, what else can a structural engineer do?"

Travel, surf, play sports, be into music, biking, kayaking, hiking, work out in the yard, hang out with friends and family, go to football games, watch too much TV, drink really good beer, puff on a nice cigar... Well that is just what this structural engineer does.

Career (sounds like this is Dick's resume): work in construction as a project manager or on site, steel fabricator, concrete pre-caster, concrete plant, specialty sales (Hilti, Simpson), tilt-wall contractor, government entity as a PM, threshold inspection, forensic engineering (mostly what I do these days), specialty engineering, aerospace engineering (if you really like FEA and mechanics of materials, yuck for me).... Yep, most of that is buildings and bridges for sure, not much dam work these days. Not sure what you were expecting, we deal with structures in structural engineering? :)

You sound a little down about your career my man. This comes with any field and with almost every person. Trust me, my lawyer friends complain plenty, my optometrist brother in law gets sick of looking at eyeballs, etc etc. Roll with the punches in these economic times and be glad you have a paycheck, and that said paycheck is derived from doing structural engineering and not landscaping or in a foundry (by far my two hardest jobs). Not every job is career building or changing, sometimes it is just a paycheck. And I don't have a lot of years behind me yet in my career, but I have gotten something out of every job I have had, including being a bag boy at a supermarket.

Take that course, maybe you'll use it directly, maybe it will just sharpen up your brain a little. It can't hurt if you are on the west coast. I sure did not need that minor in English literature but I am glad I took those classes... And if you are a single guy maybe there will be a lot of single girls in your earthquake engineering class, I heard they are virtual ladies nights...

Happy new year everyone!

I just need a change or do something.  I feel like I am just pushing projects thru and that is it.  There is nothing in it for me here and I want to be in a bigger company with more resources.  I am on the east coast in a small firm in which I think I went as far as I can.  There isnt anything that motivates me to be there except a pay check.  Yeah and I am single and plan to stay that way.

RE: Earthquake Engineering

Calif,

If you are honestly that bored where you are, I would suggest moving on.  After a while, your creativity will become stagnant...especially thinking in cookie-cutter mode over and over and over again (oh joy...another [fill in the blank]).  Since you don't have kids established in a school system, I would say to venture out...maybe leave the east coast for a while.  Bigger may not always be better.  Sometimes just a change of scenery may be just what the doctor ordered.

But...that's just my opinion.

Has anyone taken a theoretical course and earthquake engineering?  This is actually a graduate course at a university.  Unsure if the course will help with career or work though.  I here what people here are saying and I am all about learning things if I need it to but to take a course that is theoretical.  Will it help me in understanding things at work or in the field?

RE: Earthquake Engineering

Yes, as noted in my previous post, I've had both structural dynamics and earthquake engineering.  The earthquake engineering course, graduate course, covered such topics as:

* Model specific civil engineering structures to SDOF and MDOF models that are excited by real recorded ground motions.  (note that structural dynamics doesn't always have time to get into this).
* Seismicity and factors affecting ground motion characteristics
* Understanding seismic hazards, includes liquefaction and landslides and building problems,
* Response Spectra Analysis, Time History and multiple support excitation,
* Damping and yielding behavior,
* Seismic behavior of Masonry, Concrete and Steel buildings
* Code related matters

I've also taken a course in dynamics of earth materials.

There are a lot of earthquake related courses at the university.

But let me say that if you intend to limit yourself to one story steel clad buildings or  one story reinforced masonry or other material you may wish to stick with the one or two day professional courses.

RE: Earthquake Engineering

Because of the way the business side of engineering seems to work, many smaller SE firms generally deal with the same clients and may not get exposed to a great variety of work. This can work well on the economic side of things for the company, but can get a little boring for the engineers. And with the economic situation, boring is not bad as long as it pays the bills.

Interesting and exciting projects are sometimes luxuries for structural engineers, at some point to become as economic and profitable as possible most companies come up with lots of templates and things to make your job easier, but maybe more mundane. Computers further remove some of the challenges on the computational side of things. I think this would be even more true the larger the company, and you may be asked to specialize in a specific area or division. A small to mid-size company, IMHO, will offer you the opportunity for the broadest range of projects and materials. It also depends a LOT on your boss and his goals, his contacts, what he envisions your company doing. He may be with status quo and just happy riding it out with a few safe clients that don't result in too many head turning projects but always pay their bills (his goal is to make money and not make your job interesting)...

A larger company may offer bigger and more high profile projects, but I think bigger projects have the tendency to get split up into lots of pieces and you may only be involved helping a project manager with one portion. But maybe that is what you want, so you can work your way up into their position and be the lead engineer on big projects. I've been there, and that can be enjoyable too.

Personally I prefer small to mid size projects that I do mostly myself with input from other engineers as needed. I prefer a lot of variety and don't want projects that go on for several months, if they can be avoided.

Then one day you could finally get that super challenging project with an uber creative architect, and all it ends up getting you is gray hairs, long hours and less sleep :)

You have to find out what works for you, and no parent, buddy, mentor or random guy down in Florida from a message board can lead you there. You have to find out what makes you look forward to going to work every day (or at least not grimacing at the thought on Sunday evenings). To me it is all about balance and in no particular order:
-geographic location
-bosses and coworkers
-money and benefits
-type of work
-career opportunities / ability to advance
-independence
-hours (regular 8-5 or every other weekend against deadlines?)

And these can all change, they have for me in my life and career. Right now I am about to start a family and am still concerned with the econonomy- so I am OK with safe, stable, regular hours, decent pay type job.... Plenty of other ways to seek out excitement outside of work for now.

If you are in your mid to late 20s, which for some reason I get that vibe, and are not too tied down with responsibility, look for a job on the opposite coast or in a slightly different industry or in another country, why not? You have your whole life in front of you, and you are not sure what you want.   

Or if you can swing it and MAN I wish I would have done it, sell everything you own and go see the world for at least a year or as long as you can afford it. It will open your eyes in ways you have never imagined, and likely refresh you and help you figure out what you want to do. Even if you have travelled or lived in another country, pick a new part of the globe and get out there and out of your element. Go someplace with weird foods, different languages, and at least a few places that are less financially blessed as the US.

At the very least, you will have gained some valuable perspective, and perhaps even that same job (or similar) will become a good place to hang your hat while seeking out other new adventures. You may discover you have one of the most interesting careers out there in one of the greatest places in the world!

(off my soap box now, good luck my man with your life decisions)
