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 domestic steel structure and related design specifications lacks systematic rules for the performance safety and seismic performance of long-span steel structures and joints. Proposed the performance ductility design objectives and control indicators, and proposed long-span steel structure design based on ductility design seismic performance design, combined with the Guangzhou Asian Games City Gymnastics large-span steel roof design, the system expounded ductility design and seismic design The realization process and control index.
