1) Do you have a regular double IGU, or do you have a triple IGU? Regular IGU's are covered by ASTM E1300, though I suppose you could use the spirit of the code and split the load between lites according to their thickness cubed.
2) You can just treat the glass like a simply supported beam, and...
ishvaag: I can't find the mathcad document you are refering to. It sounds good though, so if you could email it to me at mludvik@hardesty-hanover.com, I would appreciate it.
dik: You make a good point about the applicability of plastic hinges to my structure. One thing i would like to establish...
If you are using kN & m, the units of mass will be metric tonnes (1000 kg). So if you have a weight of 100kN, the mass will be 100/9.8 = 10.2t.
The rule for the units of mass is you take your units of weight, and divide by the acceleration due to gravity in the units of length you are...
I am currently trying to determine the plastic hinge properties of a bridge pier with precast post tensioned segments. Plastic hinges will form at the base of the piers under high seismic loads, and I am trying to perform a pushover analysis.
There is plenty of guidance out there for...
Ishvaag: As you guessed, all that i need is a method of calculating the moment-rotation relationship. Is there some way of using an assumed plastic hinge length? If not, is it related to the bond length of the strand? I can calculate the moments at which the section will yield and the ultimate...
I am currently trying to perform either a pushover analysis or non-linear time history of a bridge with precast post tensioned piers. Plastic hinges will form at the base of the piers under high seismic loads, and I am trying to determine the properties of this hinge.
There is plenty of...
JTMcC,
Sorry for being slow getting back but I was on vacation. Also sorry didn't recognize the amount of expertise you have in the field of the economics of construction. You obviously know what you are talking about.
So I've been digging around for some hard data on exactly what construction...
JTMcC, 12% to 20% sounds like what contractors use for overhead + profit, which is frequently confused with straight up profit. Overhead includes head office, jobs which they lost money on etc. Are you sure is wasn't O+P that you read about? Insofar as I'm aware, no highway contractor of any...
The answer to your questions depends on which business you are in. I'm assuming you are a consulting engineer PorkChopBaby. You can expect about 5% over the long run. 10% in this business is considered great.
Management consultants get about 30%, lawyers do about the same, and contractors do...
As StephenEd points out, it is a matter of the connection type - is it a full moment connection between the beam and the column? Secondly, if the columns are long and slender they will not provide much rotational fixity, but if they are short and fat they will.
If you assume the supports to be...
You can think of HIH as Australia's answer to Enron.
HIH was the largest insurance company in Australia, and it collapsed recently in a blaze of scandal. The American equivalent would be AIG (American International Group) going under. The thing was that even if you got your insurance through...
I'm not a geotechincal engineer, but possibly i can offer some comment anyway.
I certainly agree with you that fees should go up to account for increased insurance premiums. It like a game of chicken - who will do it first? If you do it first and noone else does, you are in big trouble. You...
Thanks jtstruct and ClydeMule. I think I will get some of the ppi2pass stuff. As you rightly point out, practice questions are the key, and I need to get my hands on some good ones. I also work with a structural firm doing seismic analysis as it happens. I haven't worked on any California...
Does anyone out there have there have experience with the CA PE? Because of the peculiarity of my situation, I have the option of taking the PE pretty much anywhere in the country except where I live (NY). I am a seismic guy by profession, so taking the additional California seismic portion of...
