| 摘 要： | 应用ANSYS软件对屈曲约束支撑钢框架（BRBFs）和普通支撑钢框架的抗震性能进行有限元数值模拟，对比分析了这两种体系大、小震的时程响应，结果表明，在小震作用下两种结构抗震性能均表现良好，但在罕遇地震作用下普通支撑钢框架刚度退化，而屈曲约束支撑钢框架则能降低结构的地震响应。

| Abstract: | This article carries on finite element numerical value simulation for the BRBFs and common steel bracing frame by applying ANSYS software,analyzes and compares time-history response of two systems under condition of big and small earthquake.Results show that the seismic resistance performance of two structures are good under small earthquake,but the rigid will reduce under unique earthquake for common bracing steel frame,and BRBFs can reduce the earthquake response of the structure. |
