摘要
The superior design solutions (SDSs) of seven-story steel office buildings complying with the US seismic design standards (USSDSs) are compared with the SDSs using the Japanese standards (JPSDSs). Both SDSs are obtained in the same optimization algorithm for a space frame system and perimeter frame systems in moment frame (MF) and those with buckling restrained braces (BRBF). The lateral stiffness in MF required in USSDSs is 45% of that in JPSDSs and the lateral strength in BRBF is similar between JPSDSs and USSDSs with relatively greater strength in the main frames in USSDSs. © 2023 Architectural Institute of Japan.
