Hello. I was surveying a 3-story, terra cotta building with stucco exterior. The building has plenty of random hairline cracks, apparently due to shrinkage. At the bottom corner of one of the windows there is a horizontal crack, approximately 8'-10' long, located directly at the bottom corner...
I am designing an underground corridor which connects two buildings. The walls are reinforced concrete basement-type retaining walls. The floor is a concrete slab on grade. There is about 2 feet of soil above the roof of the tunnel. I am trying to decide if the roof should be a one-way...
Can diaphragm shear forces be transferred from WF beams to slab (on metal deck) diaphragms, and vice versa, within the same diaphragm?
Here is my situation:
I have (2) diaphragms that are interrupted by a slab opening. The girders run through the opening but they are unbraced (not attached to...
For all-bolted single-angle connections can you confirm that I have calculated the connection capacity correctly?
Per AISC Table 10-10.
For 2 (3/4") bolts (LRFD design):
phi*(Rn) = C * phi(rn)
phi*Rn = 1.03 * 15.9 kips
phi*Rn = 16.4 kips
Is the 16.4 kips the total connection capacity? Or do...
I have a CMU elevator core that I am using to resist lateral loads. I have been assuming that the 2 walls in the x-direction resist the loads in the x-direction, and the 2 walls in the y-direction resist the loads in the y-direction.
Can I assume that all 4 walls of the core are acting as a...
