半刚接钢框架内填RC墙结构(简称PSRCW)是一种抗震性能优良的新型组合结构体系,为推广其工程应用,文中提出了PSRCW结构的两阶段抗震设计方法:1多遇地震水准下结构的弹性设计法——用于初步确定PSRCW结构主要受力构件的截面;2罕遇地震水准下结构的能力设计法——用于确保PSRCW结构进入弹塑性阶段出现理想的破坏模式。根据已有的试验结果,提出PSRCW结构的理想塑性屈服机构,建立罕遇地震水准下RC内填墙周边钢构件能力设计的简化计算公式,给出设计步骤。文中设计方法的合理性验证见另文。
Semi-rigid steel frame filled with RC wall structure (referred to as PSRCW) is a new type of composite structure with excellent seismic performance. In order to promote its engineering application, a two-stage seismic design method of PSRCW structure is proposed in this paper: Elastic Design of Structures - section for the preliminary determination of the main force components of the PSRCW structure; and 2 capacity-design approach for structures under rare earthquakes - to ensure that the PSRCW structure enters the elastoplastic phase with an ideal failure mode. According to the existing test results, the ideal plastic yielding mechanism of PSRCW structure is proposed, and the simplified formula of capacity design for RC members around RC wall under rare earthquakes is established, and the design steps are given. The textual verification of the rationality of the design method can be found elsewhere.
