Hi everyone, I'm designing foundations for a transformer, breaker, disconnect switch, control building, and other substation equipment. The foundations are located above a 20m deep soft clay layer, so I want to know the settlement criteria for those equipment. I have read ASCE113 but I only...

I'm going to design a 3.5' height pedestal per ACI318-11. It has to support very small axial load.(5 kip axial, 2 kip shear, and 50 kip-ft moment) I'm curious about minimum longitudinal reinforcement. 1. I have read ACI318-14, and it doesn't tell us to check the minimum flexure reinforcement...

Thank you for every comment!

It has some equipment hang under the new beam(show as round pipe in the picture). So it has bending moment around X and Z axis due to Wind load. My question may sound stupid but I'm quite confused now. Is it OK? if I just check the bending moment capacity around X axis on the plate like this...

Hi, I want to install a new SQ tube beam under an existing beam by bolt connection. (Beam to plate connection is weld connection.) How should I determine the new plate thickness? Is considering plate tearing out from bolt enough? I am quite concern about the moment force on the plate. How...
