摘要：
Tins paper presents a numerical method for three-dimensional seismic response analysis of a frame containing member failure. The analysis is performed with cancellation of a large unbalanced force vector caused by a sudden fracture of members in the dynamic elastoplastic incremental analysis of a frame. A redistribution of member forces of early fractured low ductile member into the remaining members of the frame is done in each step. The validity of proposed method is verified through the numerical experiments on one-bay one-story braced steel frame and full-scale four-story steel building. © 2020 Architectural Institute of Japan.
