摘要
介绍了碟簧-钢绞线自复位防屈曲支撑及其受力特性,通过有限元软件Abaqus建立数值模型,研究支撑滞回性能、自复位特性以及耗能能力。研究结果表明:碟簧-钢绞线自复位防屈曲支撑具有较好的滞回性能、耗能能力及自复位特性,该支撑的自复位性能随着复位比及刚度比的增加而提高,耗能能力随复位比及刚度比的增加而减少。
This study introduced the configuration and mechanical behavior of a novel self-centering buckling-restrained brace with disc springs and steel strands(DS-SCB).A series of numerical model of DS-SCBs were developed to study its hysteretic behavior,self-centering and energy dissipation capabilities based on the finite element software Abaqus.Results showed that the DS-SCBs exhibited good hysteretic behaviors,energy dissipation and self-centering capacities.The self-centering capacity of the DS-SCB can be enhanced with the increase of self-centering ratio and stiffness ratio,and its energy dissipation capacity decreased with the increase of reset ratio and stiffness ratio.
