Thanks all for the replies. If anyone has an example calculation or article on stiffness analysis for reshoring that would be helpful. So far I have not been able to find any example calcs. I'm thinking the stiffness of reshores could simply calculated using k=A*E/H but determining slab...

When reshoring a multistory building with many levels of reshores (5+ levels of reshores), how much load would the lower most slab experience from the loads on the top? Using diagram sketch, there 5 levels of reshores and 6 interconnected slabs. When the 7th floor is poured would the bottom most...

I'm trying to analyze a custom made "lifting cap" to find the safe working load. This consists of a 16" diameter steel caisson 12" long with 0.565" thick walls welded to a 1" thick plate (at bottom). The caisson is threaded at the top and will be attached to a rig. The eyelet is 2 inches thick...

Thanks for the input! All metal is A36 steel and welding using E70XX electrodes. The angle cantilevers out for a 5 feet and will take about 200 lb ultimate load (osha temporary guardrail). So there will be a bending moment on the weld/base plate connection. For bolts I was thinking two 5/8...

If I use a 1/4" fillet weld all around on a 4x4x1/4" thick angle to connect to a base plate, is it safe to say the weld is as strong as the angle? Since the area of the weld will be equal to the angle. The angle will have an eccentric load so there will be bending stress. The section modulus...
