Is there a program (similar to Ram Structural System) that will aid in the design of wood shear walls? I'm looking for a program where I can build a 3D model of the building (with window/door openings in the walls), apply the lateral loads, and get the most efficient shear wall layout. Any tips?

When modeling an ordinary steel moment frame (I'm using RAM Frame), should I pin the beam ends in torsion?

I am a structural engineer and a new P.E. My boss has asked me to inspect one of our concrete jobs. So I went out and made test cylinders and did a slump test, along with my other duties. Well, the contractor came over to me and asked me if I had a certificate that allows me to make the...

If a retaining wall is permanently exposed to earth, shouldn't the concrete cover be 3"? Why am I seeing so many engineers use a 2" cover?

Should I be adding snow load to the top of a roof top unit? If so, do I add the minimum roof live load (30psf) or the flat roof snow load (~20psf)? My RTU is covering 460 sf of the roof, at 30psf, that's an extra 14 kips I need to account for. Engineers I know seem to have different views...

I have an existing 2 way slab with drop panels. The bays are 28'x28'. We are installing steel beams (with adhesive anchor) to the underside of the slab to frame out a large opening. The opening will be cut in the column strip. The opening is 7 feet wide (so it will take out the portion of...
