摘要

摘要: 为了改善传统约束屈曲支撑的不足,提出双T型内核与角钢约束机构共同构成的新型约束屈曲支撑。利用有限元分析软件ANSYS,建立该新型约束屈曲支撑有限元分析模型,并对其进行低周反复荷载全过程非线性有限元分析。主要考察芯材与约束机构间的间隙、约束刚度、连接段以及过渡段长度等主要参数对其滞回性能的影响,并给出各参数的建议取值,为新型约束屈曲支撑设计提供参考。

Abstract: To improve the traditional BRB,it was proposed a double-T-shaped core member and angle iron bucklingrestrained brace( DTABRB). Using ANSYS software,finite element model of DTABRB was created. The nonlinear finite element analysis( FEA) is carried out on the model under cyclic loading and hysteresis loop of brace was obtained from FEA. Based on which multi-parameter analysis,considering different gap between the steel core member and the buckling-restrained mechanism,restraining stiffness,the length of connection section and transition section was carried out to study impacts of these parameters on hysteresis loop of DTABRB. Finally,the suggested values of these parameters were given,which provided a reference for the design of the new brace.
