Abstract: The current Chinese steel design code and other relating design specifications lack the systematic regulation on the safety performance index for large span steel structures at the joint and system levels as well as the performance-based seismic design of structure. The target and controlindex of the ductility performance-based design were carried out. The seismic design of span steel structures is advised to use the performance-based design. At last, this paper systematically illustrated the process of ductility and performance-based design and use of the control index with the Asian Games Gymnastics Stadium structure system in Guangzhou which is a large span steel structure.
Keywords: large-span steel structure; ductility performance-based; performance-based seismic
