(a) The uniformly distributed live load on all four floors in figure below is 70 lb/ft² and considering any live load reduction if permitted by the ASCE standard. Establish the live loads and free body diagrams for members (a) floor beam B1, (b) girder G2, and (c) calculate the axial forces produced by the live load in column C1 in the third and first stories. (b) Determine the wind pressure distribution on the four sides of the four-story building below assuming wind is acting in the north-south direction. The building is located near the Georgia coast where the wind velocity contour map in the ASCE Standard specifies a design wind speed of 140 mph and exposure D applies. The building, located on level flat ground, is classified as stiff because its natural period is less than 1 s, therefore, the gust facto G =0.85. The importance factor is 1.0. The building is located on the level ground then K-1. Assume Ka=0.85. On the windward side, evaluate the magnitude of the wind pressure every 12 ft in the vertical direction.
