I have an opportunity to work as a sub-consultant. I want to register an official business with my state. I'm a licensed engineer but would not be stamping any of the work I would be doing. From what I'm reading, that means I can just register as a consulting firm as a limited liability...
Does anyone know the OSHA design loading requirements for temporary stairs used on a construction site? I know this falls under OSHA 1926.1050 - Stairways and Ladders but no loads are given. There is a different section of OSHA stating that the capacity needs to be 5 times greater than the...
I have a scenario that I would others to weigh in on. It's completely hypothetical, but led to a debate among peers.
Scenario:
Worker "A" provides calculations for a project that Worker "B" stamps with the P.E. seal. Worker "A" does not work for Worker "B" or his firm.
Did Worker "A"...
Does anyone know of a good resource that covers the design/analysis of T-walls?
Here are a few screen shots since I know the first things engineers need is a sketch [bigsmile]:
Does anyone know of any guidance on how to treat a "triangular" soil mass that is resting on a vertical wall?
The following is a simplified version of my problem:
The initial analysis is assuming that there is sediment build-up to within 2' of the wall and they treated it as level backfill...
Can anyone recommend a good reference book for explaining simple things like gear ratios, rpm, etc. for simple systems? I did take a class in college, I think it was Dynamics, but that was 20 years ago and I don't recall getting too deep into mechanical stuff. I'm involved in a movable bridge...
Does anyone have experience with area loads in the Shoring Suite software?
The user manual section 9.4:
9.4 Area Loads
"Buildings and large equipment are typical area loads. When they are placed near a sheet pile wall, the lateral pressure distribution on the wall can be calculated as shown...
Does anyone know where in the ACI code the specific definition of a two-way slab is? Dr. Google says you assume two-way action when the ratio of the long span to the short span is less than 2.0, but my textbook says 1.5. I can't find the definition in ACI318-14 which seems strange.
The attached photo is for an expansion bearing on a pedestrian truss bridge. The masonry plate and elastomeric portion came as a unit, were installed over the anchor bolts. The truss was then set down and the plate on top of the bearings is welded to the end post of the truss. Both plates...
Does anyone know how to determine the allowable torsional shear stress for steel? I don't believe AISC is a good resource as my situation is related to steel shaft design. I can easily determine the applied shear stress, but I have nothing to compare it to. My old college textbook just states...
I’m checking a design for Noise Wall. The designer is using a simplified soil pressure distribution, I’ve attached a sketch. The foundations are essentially drilled shafts. The designer did something I’ve never seen before for this type of design. He took the area of the circular shaft...
Help! A young coworker is studying for the PE exam and asked me for help with this problem. I did what I thought was correct in a few minutes only to find out my answer was not correct. Just curious what everyone else gets for an answer. See attachment...

In designing a concrete tremie slab for a cofferdam I am coming up with a really thick slab. One of the geotechnical engineers I work with said that I can reduce the thickness by taking advantage of the bond between the tremie concrete and the new piles. He also indicated...
