    Project Team Jumps Ship. I'm left with New Owner

    I'm not sure if I would hang around under those circumstances. A guy who runs his company like that.....he's not trustworthy. I've had to separate myself from those kinds of companies. And I am better off for it. Just let this guy start over from scratch.

    Non-Paying Clients

    I think you can file a lien. But for the long haul: I'd just stay away from residential. Where I live, most engineering companies avoid it. Biggest bunch of deadbeats you'll find is in residential. At one company I worked for (that actually did it): the office manager had drawer in her desk just...

    Archived Threads

    I cannot find the threads I had archived under the old platform.....anybody know where that is?

    SE Exam New format April 2024

    It is closed as far as: I can't bring in any reference material. I couldn't imagine sitting there and flipping through some (unmarked) pdf (or whatever) to find what I need.

    SE Exam New format April 2024

    I remember that! The funny thing about that was (around that time): the gears switched on that. (IIRC around 2002-2004.) All the sudden the SE I & II pass rates switched. I.e. prior to that point, the SE I had high pass rate and the SE II had a low one. But that switched right around the time...

    SE Exam New format April 2024

    I guess that is possible....but when I was going through the SE I & II, I had a BS & MS (under the "old" system), and I had a hard time passing the SE I. In fact, the pass rates then are comparable to what they are now. So I don't know that I buy the education theory. If they gave me a closed...

    SE Exam New format April 2024

    I agree.....but I have to question those pass rates. Why are they so much lower than other disciplines? Either one of two things are going on: the colleges are turning out lousy engineers in our discipline, or there is a issue with the test. I don't buy the former, I think it is the latter. It...

    AISC VS rigorous buckling analysis

    I didn't sift through all the replies (so someone may have already said this).....but this caught my eye. You are in the wrong code for shells. AISC is not meant to address them. The safety factors for shell buckling can get very high (on the order of 10 to 20+) since initial imperfections can...

    Taking the PE exam before experiance

    Well technically, they won't be licensed until they get the experience (even if they pass the exam immediately after college). But practically speaking, (if we are talking the SE exam) I'd be surprised if anyone would pass that thing right out of school or just with a few years experience...

    Weld Stress in Built Up I-Beam

    I don't get the question....stress from what exactly? Residual (from welding)? Stress from applied load? Or something else?

    Understand a dynamic load representation

    Yes. (All three.) VM-6370

    Understand a dynamic load representation

    You can get some good bang for your buck with them. (I.e. a device for around $300.) Vibration equipment can get pretty outrageous in terms of cost.

    Understand a dynamic load representation

    Measure, as in the field? I have a device (made by LANDTEK) that is pretty good at measuring vibrations (as long as the forcing frequency is 10 Hz or more). The info it is going to get is kind of limited (without more equipment). If i need a lot of (highly detailed) info.....I'll hire a third party.

    Connection deisgn for for weak axis moment/shea

    Anytime. Btw, something I forgot to mention: check the web carefully for this load transfer (to the shear angles acting as a seat in this direction). Sometimes the web can severely limit the amount of load that can be transferred.

    Connection deisgn for for weak axis moment/shea

    I've typically used the moment connection to transfer both strong & weak axis moments to the columns. It's just a matter of proportioning the utilization(s) for each case. (I.e. you used up X % of the capacity for the strong axis and Y% for the weak axis. Just make sure X+Y<100%.) The procedures...

    Understand a dynamic load representation

    Depends on the equipment.....and also the number of times it ramps up & down during it's use. I was brought it on one project (this is a specialty area of mine) where the equipment was having maintenance issues because of trasient motion that was not checked. This thing started up & ramped down...

    Understand a dynamic load representation

    There is a very real possibility that you will pass through a resonance frequency (for either the equipment or the supporting structure) during start up. (Note I say "a" resonance.....since there are multiple frequencies involved for such a system.) I normally check the displacements with a...

    Beam Stiffeners

    It is hard to say without knowing more than I know now. It would certainly stiffen things up (locally)- where you do have stiffeners. In a vibration problem, you are looking for a landmine....only calculations tell you where that is. (I.e. stiffening things could actually make the vibration...

    torsion - measuring deflection in radians

    Do you have 'Roark's Formulas for Stress and Strain'? He has a lot of formulas for it. If we are talking about a circular cross section, the formula is: Φ=TL/JG Where: Φ= rotation [in radians] T=applied torque L=Length J=Polar moment of inertia G=Shear modulus

    Beam Stiffeners

    Agree with centondollar: web stiffeners will not change the torsional stiffness of the beam. I did a FEA study on this some years back.....and you have to add a impractical number of them to make a difference. I like the brace idea others have proposed.
