基于滑楔连接的新型填充墙设计与抗震性能数值模拟

为了减轻填充墙与框架在地震中的不利相互作用,提出一种采用滑楔连接件的柔性填充墙框架结构设计方案.采用ABAQUS建立滑楔连接框填结构有限元模型,与满砌填充墙在平面内滞回性能、平面内外耦合性能、墙框局部损伤及填充墙整体损伤等方面进行了对比分析.模拟结果表明,和满砌填充墙相比,采用滑楔连接减轻了填充墙与框架平面内相互作用产...

Design and numerical simulation on seismic performance of novel infilled wall with sliding connection

In order to reduce the adverse interaction between the infilled wall and the surrounding frame in the earthquake,a design scheme of a flexible infilled frame which adopts the sliding connectors is proposed.The FE model of the infilled frame with sliding connection is established using ABAQUS,and the comparison as well as analysis are conducted with the infilled frame with rigid connection in terms of in-plane hysteresis performance,in-plane and out-of-plane coupling(IOC)performance as well as local damage condition of the structure.The simulation results show that the sliding connection can reduce the local damage caused by the interaction between the infilled wall and the frame,and has has higher ductility as well as better IOC performance,providing a new solution for the resilient design in terms of infilled frame system.
