钢板剪力墙作为一种新型的侧向支撑结构体系,由钢框架内嵌钢板组成,具有初始侧向刚度大,滞回性能稳定,耗能好,延性大等优点。目前关于梁柱连接对该体系整体性能影响的研究较少,且均是假定连接为完全刚性或理想铰接。从设计模型、规范、试验和理论分析等方面全面阐述了近年来国内外学者的研究成果,提出了半刚性框架-钢板剪力墙新型结构体系。该体系在利用钢板剪力墙作为侧向支撑体系的同时,考虑了框架连接中半刚性节点的性能,既可以更真实地模拟连接的特性,实现内力重分布,提高框架的经济性,又可以在满足结构侧移要求的前提下简化节点构造,提高施工效率。算例中将平齐端板连接应用于钢板剪力墙结构中,证实了半刚性框架-钢板剪力墙结构体系的实用性与经济性。
As a new type of lateral support structure, steel plate shear wall consists of steel plate embedded in steel frame, which has the advantages of large initial lateral stiffness, stable hysteresis, good energy dissipation and large ductility. At present, there are few studies on the influence of beam-column connection on the overall performance of the system, and all assume that the connection is completely rigid or ideal hinged. From the design model, norms, tests and theoretical analysis of comprehensively expound the research results of scholars at home and abroad in recent years, put forward the semi-rigid frame - a new type of steel shear wall structure system. The system uses the steel plate shear wall as the lateral support system, and considers the semi-rigid joints’ performance in the frame connection. It can simulate the connection characteristics more realistically, realize the redistribution of internal forces and improve the economic efficiency of the frame, Under the premise of meeting the requirements of structural side-shift, the node structure is simplified and the construction efficiency is improved. In the example, the flush end plate connection is applied to the steel plate shear wall structure, confirming the practicability and economy of the semi-rigid frame-steel plate shear wall structure system.
