Q1 Figure 1 shows the elevation and main floor plan for a five-story building. The building is clad with nonstructural precast panels. There are no structural walls or other bracing. The floor beams in the north-south direction is all 18 in. wide with an overall depth of 30 in. The floor slabs are 6 in. thick. Assume all the floors are to be designed for a superimposed dead load of 20 psf plus a live load of 80 psf, which includes a 20 psf partition loading. The roof is assumed to have similar-sized structural members, carries a superimposed dead load of 25 psf, and has a reduced live load of 30 psf. Design an interior and exterior column in the first-story level for dead load, live load, and wind forces in the north-south direction. Assume we are using "service-level" wind forces, so the appropriate load factor is 1.6. Use fe' = 4,000 psi and fy = 40,000 psi.
