Question

PROBLEM 3: (40points) Figure shows te clevation and main floor plan for five-story bailding. The building is clad with nonstructural precest pansl There are no sructural walls or other bracing. The floor besms in the north-south direction are all 450mm wide with an overa depth of 750mm. The floor slabs are 150mm thick Assume all the floors are to be designed for a superimposed dead load of S KPa plus alive load of 12KPa, which includes a 3.5KPa partition loading. The roof is ussumed to have similar-s structural monter, cames a superimposed dead loud of İkPa and has a reduced ive load uorosokh has a nene and exterior columin in the firt-story level for dead load, live load, and wind forces in the north-south direction, Assume we are using "ervice-levelr" wind forees, so the uppropriate load factor is 1.6. Use fc-27.6 MPa and ty-414 MPa.
