摘要
为提升钢框架-复合墙的力学性能,文中设计一种新型的U形连接件,通过Abaqus模拟仿真软件对装配式自复位U形连接件改造后钢框架-复合墙的结构性能进行仿真分析.结果表明,单轴压缩下U形连接件荷载-位移曲线先近似线性增加后平稳;单轴拉伸下U形连接件荷载-位移曲线先快速增加后缓慢增加,荷载位移曲线为双折线阶段;水平段长度越小,U形连接件承载值越大,耗散性能越强.加载前期,U形连接件改造的钢框架-复合强结构残余变形较小,具有自复位能力及优良的耗散性能.
Abstract
In order to improve the mechanical properties of steel frame-composite wall,a new type of U-shaped connector was designed in this study.Abaqus simulation software was used to simulate and analyze the structural properties of steel frame-composite wall after the transforma-tion of assembled self-resetting U-shaped connector.The results show that under uniaxial compression,the load-displacement curve of U-shaped connector first increases linearly and then becomes stable.Under uniaxial tension,the load-displacement curve of U-shaped connector increases rapidly at first and then slowly,and the load-displacement curve is a double-fold line stage.The smaller the length of the horizontal section,the larger the bearing value of the U-shaped connector and the stronger the dissipation performance.At the early stage of loading,the steel frame-composite strong structure modified with U-shaped connectors has small residual deformation,self-resetting ability and excellent dissipation performance.
