| 摘 要： | 通过3个算例,对采用人字形和V字形的无粘结内藏钢板支撑剪力墙(即人字形和V字形防屈曲支撑)的防屈曲支撑钢框架结构的抗震性能进行分析。重点考察大震下,支撑的轴力分布和对被撑柱所受轴力的影响。分析表明,采用结构在一阶振型下的支撑轴力分布来设计被撑柱的做法,适用于多层的防屈曲支撑钢框架结构;而对于高层的防屈曲支撑钢框架结构,高振型影响较显著,上述设计方法对被撑柱的设计较保守,有必要考虑高振型参与下的支撑轴力分布来设计被撑柱。

| Abstract: | A seismic response analysis on three buckling-restrained braced frames(BRBFs) has been carried out to investigate the seismic design methods of braced columns.The effects of distribution of axial force of inverted V and V type buckling-restrained braces on axial loads of braced columns are mainly examined.The analysis reveals that,generally,the design based on the first-mode response can be considered for the multistorey BRBFs.However,for the high-rise BRBFs,the participation from the higher modes is remarkable and it should be taken into account in seismic design of the braced columns. |
