阻屈耗能支撑系统工作过程和机理的有限元分析

The Limited Member Analysis of the Work Process and Mechanism of Buckling Restrained Brace

在台湾学者Keh-Chyuan Tsai对耗能支撑框架结构进行试验研究的基础上,应用ANSYS分析软件对 其中的阻屈耗能支撑(BRB)进行了单调荷载作用下三维非线性有限元模拟。通过一系列的计算,对BRB系 统的核心耗能钢板、无粘接混凝土和约束钢套筒的工作过程和机理进行了全面的分析,为抗震设计提供理论 基础。

The paper simulates the work process of a buckling restrained brace under monotony loading through the analysis software of ANSYS, and on the basis of the experimental studies of Taiwan＇s scholar, Keh-Chyuan Tsai. By a series of calculations, we describe the work process and mechanism of a core steel member, an unbinding concrete and binding steel tube, and the afford theory foundation for resisting seismic design.
