There are two shear walls which provide all of the lateral force resistance. Assume the seismic weight Wis comprised solely of the roof DL. Ignore the weight of all other elements. Assume Cs = 0.15 Assume that of the wind hitting the south faade, goes directly into the foundation and / goes directly into the roof diaphragm. Calculate the force in each shear wall due to: Wind only Seismic load only . The following building has a roof DL which will cause a seismic load in the North direction.
