摘要(Abstract):

国内现行钢结构及相关设计规范对大跨度钢结构体系与节点的性能安全及抗震性能指标缺乏系统规定。提出结构延性设计性能目标及控制指标,并建议大跨度钢结构设计采用基于延性设计的抗震性能化设计,最后结合广州亚运城体操馆大跨度钢屋盖设计,系统阐述延性设计及抗震性能化设计的实现过程和控制指标。
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 control index 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.
