Abstract
In this paper, evaluations of earthquake response of a five stories reinforced concrete boxed wall-building using the capacity spectrum method considering structure-soil interaction are conducted. Three different soil conditions are considered in the evaluations. The horizontal strength and the ductility of buildings in stiff soil condition, the horizontal stiffness and strength of buildings in intermediate soil condition, and the horizontal strength of buildings in soft soil condition are important for the seismic safety of reinforced concrete boxed wall-buildings.
