摘要 采用ANSYS有限元软件,对双管式防屈曲支撑的性能进行模拟分析。通过模态分析和拟静力加载分析对比这两个方案的优劣性。结果表明:双管式防屈曲支撑是一种优良的耗能构件,该构件在实际应用中将销钉安装于内管中间位置效果良好,起到了固定外管位置的作用而且不影响支撑的应力分布,保持了良好的滞回耗能能力。 The performance of double-tube buckling-restrained brace is studied in the thesis by using ANSYS finite element software.Through the modal analysis and the quasi static load analysis, comparative analysis on the advantages and disadvantages of two models is made.The results indicate that: double-tube buckling-restrained brace is a kind of excellent brace with good energy dissipation capacity. It is better to install the pin bolt in the middle of double-tube buckling-restrained brace in the actual application than installing them on two side of brace. The pin bolt plays an important role in fixed outside tube position and does not affect the supportstress distribution, and keeps good hysteretic energy dissipation capacity.
