Thank you for your feedback. I will verify whether the W310 beam can take the applied torsion. AK4S – do you have any suggestions for a means to restrict torsion in this situation?

I am looking for some guidance on how to determine the tensile loads carried by sag rods in structural steel buildings. The situation that I’m dealing with is common - a frame in a structural steel building with horizontal wall girts spanning from column to column to support the weight of the...

I am analyzing the attached detail. It is a cantilevered beam that is supporting the guide rail system for the roof of a structural steel building. As you can see, the cantilevered beam is connected to a perimeter beam of the building. This perimeter beam runs parallel to the open web steel...

Thank you for the feedback. I will look into Simpson Strong walls to help resist lateral forces at the garage door. As for the long span beam along gridline 2 - to avoid incorporating a moment frame, I was thinking of adding an interior shear wall (as shown in the attached drawing). The client...

Hello, I am working on a residential project for a client that currently has a 24’ x 30’ garage. The garage is in good condition, and he would like to add an addition. He would like to remove half of the existing garage, and to the remaining 12’ x 30’ section – add a new addition. The new...

Hi Everyone, I am an engineer in training and I have a quick question regarding lateral bracing for structural steel buildings. I am currently working on the design of a standard one-storey structural steel building (square geometry, retail store). The front wall of the building is almost...

Hi everyone, Question from a young engineer in training from Canada – can a symmetrical hollow section (square in my case) undergo lateral torsional buckling? Do the out-of-plane stability design checks for beam-columns apply to symmetrical hollow sections? I am working on the design of an...

Thank you for all the responses. The only uncertainty that I encountered when going through the standard beam-column design process is regarding out-of-plane stability (i.e., lateral torsional buckling). My question would be - can hollow sections (circular, square, rectangular) be subject to...

Thanks everyone for the information and guidance, really appreciated!

Hi everyone, I'm an engineer in training from Canada that has been working in the design / analysis of buildings for 1 year now and I am new to this forum. I am currently working on the design of a very standard one-storey structural steel building (80' x 120' retail store, 14' column height)...
