Abstract

Substructure pseudo-dynamic tests were conducted to simulate story collapse of old three-story R/C buildings. The buildings were idealized to consist of a single column line and rigid beam. The first-story column that was designed to fail in shear was tested by the substructure pseudo-dynamic method where the second- and third-story columns designed enough strong were assumed elastic. An imaginary mass was determined in such that the first mode period and Seismic Capacity Index, Is, might result in 0.15 second and 0.49, respectively. Three earthquake records were used as input motions. Responses of the buildings, mostly those in the post-peak regions including collapse were studied.
