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.关键词
