| 摘 要： | 针对混合结构中下部框架结构强弱轴方向的侧向刚度差别,对约束屈曲支撑采用不同的布置方案.选择位移比和周期比作为该结构体系整体协同工作的参数,将考虑上部网架的混合结构体系整体协同工作性能进行罕遇地震下的时程分析.结果表明:双向布置的约束屈曲支撑能够明显改变位移比和周期比,提升结构体系的抗震性能,对混合结构整体协同工作性能贡献最大.

| Abstract: | The lower frame structure＇s lateral stiffness is big difference of the hybrid structure between the weak axis direction and the major axis direction,the buckling restrained brace＇s arrangement uses dif- ferent solutions. Considering the upper space truss structure system, the hybrid structure is analyzed in rare earthquake by using time history analysis, bout the hybrid structural system＇s overal way layout can significantly change the dis the structure system,and the contribution and use the displacement ratio and period ratio as parameters a- 1 work. Results show that the buckling restrained brace＇s two- placement ratio and period ratio,improve the seismic behavior of to the overall work performance is largest. |
