Consider a 7-story buildings with a total plan area BxL. In which B=125ft and L=60ft . The average weight of each floor and roof are 95 Ib/ft and 75 lb/ft?, respectively. The 84 ft-tall building is located in a seismic region with SDs =1.6 g and SD1 =0.5g for a building supported on rock, where g is the gravitational acceleration. The structure of the building consists of steel moment frames (all joints are rigid) that have an R value of 8. The importance factor I=1.0 Determine the total design seismic force (kips) acting at the base of the building ( seismic base shear in kips). ***the answer was between 339.5 and 342.5*** but I don’t understand how .
