A full-scale experiment to simulate collapse of a 4-story steel building was conducted using E-Defense shake table facility. The specimen consists of beams of wide-flange sections, columns of rectangular hollow sections, concrete slabs with deck plates, and column bases with anchor bolts. The collapsing of the specimen was characterized by deteriorating behavior caused by local buckling of column at the first story. This paper deals with the analytical simulation of the specimen based on the collaborative structural analysis system. This system is capable of performing highly sophisticated structural analyses utilizing the beneficial features of existing individual structural analysis programs. Several programs are being used to simulate various components of the whole frame. The program, COMPO, is used for analyzing composite beams that consist of steel beam and concrete slab. The general-purpose program, MARC, is used for analyzing columns of rectangular hollow sections. The program, NETLYS, is used as a host program. It deals with the global equation of motion, to which numerical information of all sub-structures is involved. The analytical results are compared with test results of shake table. The effects of structural components to overall collapsing behavior of the specimen will be discussed.
