| 摘 要： | 本文利用SAP2000对悬挂式附加阻尼装置的巨型钢框架支撑体系进行地震分析，并与巨型钢框架悬挂结构、巨型钢桁架悬挂结构和悬挂式巨型钢框架支撑体系进行对比研究。研究表明，在水平地震作用下悬挂式附加阻尼装置的巨型钢框架支撑体系比其余两种结构，显著减小结构的位移、加速度和内力变化幅值；在竖向地震作用下，悬挂式附加阻尼装置的巨型钢框架支撑体系没有出现竖向地震放大现象。

| Abstract: | The dynamic analysis of mega-suspended braced frame with damper is discussed in this paper using the finite element method.These analysis results are compared respectively with those of mega-frame-suspended structure and mega-truss-suspended structure.It is proved that the displacement and accelerate velocity of the high point of mega-suspended braced frame with damper are less than the other three structures,when acted by one dimensional horizontal earthquake.The mega-suspended braced frame with damper doe... |
