A numerical method for dynamic analysis of multistory steel space frames is presented. The frame is idealized as a multistory, lumped mass, rigid floor system. Three degrees-of-freedum per story, two horizontal translations of the mass center, and a rotation about the vertical axis are considered in dynamic response. The restoring forces of the frame are obtained by solving whole structure using the previously reported numerical method. Therefore, the influence of the large deformation of the frame and the axial deformation of columns on the restoring force characteristics can be evaluated. The accuracy of the method is examined on the responce of single-story, single-bay and three-story, single-bay space frames subjected to simultaneous action of two horizontal components of sinusoidal ground acceleration.
