MC: What do you mean by short/long direction? The 2' direction? I hadn't thought about that, was imagining a deeper beam (~2') but I guess with some short bars I could get away with a 12" depth with some short steel.
But the stiffness of the footing is an issue right? If I turn the beam upside...
I'm working on a strip footing for a small commercial building. Soils are medium-dense sand with a bearing capacity of 2,500 psf for strip footings and a max strip footing width of 2'. The building footprint is 28' wide and while I can extend the footing on one side about two or three feet, the...
KK: Thanks for reminding me of my FEM professor! Might hit him up for a nailing pattern on this one. I am getting close to working out a solution by hand so I have a pretty decent sense of how this is working out. The diaphragm has huge in plane shear stiffness on account of the short span (16')...
T,
That's where I started. Problem is, the 2-2x10s don't work. They barely carry the dead load with that method and after doing that calc I was worried the structure would collapse. After some thought, I figured the girders are picking up some extra strength from two different sources...
Long time reader, first time post. Nice to join you all!
I'm looking at a rehab of a 110 y.o. social hall. The main room is 60 feet wide and covered with a sloped (6.8/12) roof. The structure is new to me. Massive steel trusses cross the 60' span every 16 feet (they're very rigid). Doubled...
