摘要

针对多自由度复杂体系的网壳结构的抗震性能,提出了设置屈曲约束支撑的新型网壳减震体系。通过理论分析与数值模拟的方法证明了此新体系良好的抗震性能,进一步利用网壳结构缩尺模型进行模拟地震振动台实验研究以验证其性能,并分析新型网壳减震体系在不同水准地震作用下的动力特性与减震耗能性能。理论分析和实验结果表明,在地震作用下设置了屈曲约束支撑的单层球面网壳地震响应有所减小,屈曲约束支撑起到一定减震耗能作用。

Abstract

New dissipation system of reticulated shell structure with Buckling Restrained Brace (BRB) was proposed for seismic performance of reticulated shell, which is one kind of multi-degree-of-freedom complex systems. The new dissipation system was analyzed on performance of earthquake resistance by theoretical analysis and numerical simulation, and the shaking table test was made by reduced scale model to simulate dynamic characteristics and dissipation capacity under different levels of seismic action. The result shows that the seismic response of Kiewit dome with Buckling Restrained Brace decreases and the effect of dissipation of vibration with Buckling Restrained Brace are clear.
