| 摘 要： | 借助有限元软件ANSYS,考虑实际屈曲支撑的受力特点,利用有限元分析方法妥善处理套管填充物与核心之间的接触问题,将该方法计算结果和屈曲约束支撑试验中提供的结果进行比较,验证了有限元分析方法研究屈曲约束支撑极限承载力的可靠性,突破了目前屈曲约束支撑的研究主要依赖于试验和理论分析的现状。

| Abstract: | Taking the practical mechanical property of the buckling-restrained braces (BRBs) into consideration by the ANSY S, the contact problem between the mortar of tube and the steel core was properl y ha ndled by finite element method. The results of the finite element method (FEM) are compare with the res ults provided in the experiments of BRBs, and it proves the reliability of the F EM in investigating the critical bearing capacity of BRBs, and exceeds the present state of investigation relying on the experim... |
