摘　　要： 针对提出的可恢复功能的装配式预应力钢框架结构体系,依据已完成的梁柱节点、框架试验和整体结构的分析结果,结合我国现行建筑抗震设计规范,提出了腹板摩擦耗能的可恢复功能的装配式预应力钢框架"多遇地震无开口、无损伤,设防地震开口耗能且主体结构无损伤、罕遇地震主体结构损伤较小且仍能正常使用"的性能化设计目标,同时提出了性能化设计准则和设计流程,并通过设计算例验证了该方法的可行性,证明了提出的装配式预应力钢框架的结构响应估算方法具有一定的可靠性。 For the proposed resilient prefabricated prestressed steel frame structural system,the performance-based design objectives of the resilient prefabricated prestressed steel frame with web friction damper are put forward that there are no opening and damage under the frequent earthquake,the joints could dissipate energy by gap-opening and protect the main structure from any damage under the design earthquake,as well as the main structure maintain serviceable with little damage under the rare earthquake.The study is based on the completed frame test and integral structural analysis and the current code for seismic design of buildings of China.In addition,the relevant performance-based design criteria and procedure are proposed.The design calculation example shows the feasibility of performance-based design method,verifying the reliability of structural response estimation method toward resilient prefabricated prestressed steel frame system.
