I was wondering if anyone else had come across the slight change in ACI 318-19 to the calculation for the effective moment of inertia for non-prestressed sections. I ran across it while trying to replicate an existing design but using the new code and my concrete beam deflections shot way up...
I have seen a few threads on here regarding the new one-way shear (reduced) capacity for slabs and pile caps in ACI 318-19. This change is seemingly only now coming to the forefront because more municipalities are adopting the 2021 IBC. I have not seen a thread yet regarding one-way shear...
I have a few questions on what others do in calculating the deflection of a wood shearwall. In my specific case I am looking at the deflection due to wind.
1. In the 3-term deflection equation in SDPWS, it uses Ga (apparent stiffness). For seismic conditions this value is given in the nominal...
I don't work a lot with wood but currently have a project utilizing LSL rimboards beneath wood framed walls, some of which will be shearwalls. I understand the mechanics of the shear transfer from the wall above using 16d nails from sole plate to the LSL and from the diaphragm to the LSL via...
