基于ANSYS约束屈曲支撑框架结构分析

摘要

传统的耗能支撑框架结构具有较好的经济性,但是,在中震和强震时,支撑会发生受压屈曲.利用ANSYS模拟约束屈曲支撑框架在地震作用下的结构响应,采用理想弹塑性模型模拟屈曲约束支撑的滞回性能,分别在中震烈度和大震烈度下,对一般框架结构和约束屈曲支撑框架结构进行非线性时程分析,得到结构响应.分析结果表明,约束屈曲支撑结构减震效果良好.%The traditional energy support frame structure with good efficiency, but in moderate earthquakes and strong earthquake support will occur pressure buckling. Using ANSYS simulation buckling-restrained brace framework response of the structure in earthquake. Using the ideal elastic-plastic model describe buckling-restrained brace hysteretic performance, in moderate earthquakes and strong earthquake, general framework and buckling-restrained brace framework for nonlinear time-history analysis, solving structural response. Analysis results show that buckling-restrained brace structure damping effect is good.
