Hello all,
I'm analyzing a mat foundation in STAAD and would like to get input on the subgrade modulus being used. I'm using plate mat foundation supports in the Y-direction in STAAD. The geotech report stated a unit subgrade modulus of 150 pci and suggested that the subgrade modulus be...
Hello,
I am modeling an existing, large storage structure with precast concrete columns, steel girders, steel purlins, and metal decking. I'm focused on modeling the steel framing members to determine member forces. The girders are fastened to the top of the precast concrete columns and the...
Hi JedClampett. I saw an old post of yours from 2013 on tanks, so good to see you are still active. AWWA D110 is Wire & Strand Wound, Circular, Prestressed Concrete Water Tanks.
I found a few large concrete tank manufacturers (DN Tanks, Crom, Preload), but steel tank manufacturers seem to be...
Hello,
I am working on a water storage tank project in the intermountain region of the US (WY, CO, UT, etc.) and I am looking into the different types of tanks. I have little experience with water storage tanks and the ones I am familiar with are AWWA D110 Type I for high seismic regions. Are...
Does the "De-stabilizing load" account for the de-stabilizing load of the slab and the structure it is supporting or just the structure above the slab? I have attached a simplified diagram for reference...
Hello,
I am checking the overturning stability of a slab-on-grade supporting a pipe support. I am checking the overturning about the bottom edge of the slab, which is 14" below finished grade. My resisting force is the sum of the vertical load (weight of pipe and concrete slab). My question is...
