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。
Aiming at the prestressed steel prefabricated steel frame system with recoverable function, based on the analysis of completed beam-column joints, frame test and overall structure, combined with the seismic design code of our country, Restoration of prefabricated prefabricated steel frame “performance of the earthquake without opening, no damage, fortification earthquake opening energy consumption and the main structure without damage, less damage to the main structure of the main earthquake and can still be used normally” design The design criteria and the design flow of the prefabricated prestressed steel frame are presented. The feasibility of this method is verified through the design of a numerical example. It is proved that the proposed method of estimating the structural response of the fabricated prestressed steel frame has certain reliability.
