【摘要】 本研究通过对某超高层结构模型进行模拟地震振动台试验,考察核心筒、外围框架与伸臂结构组成的抗侧力体系在地震作用下的整体抗倾覆性能,重点分析在伸臂结构设置黏滞阻尼器的消能减震策略对结构底部弯矩的控制效果,为该类超高层结构体系减震研究提供参考。更多还原

【Abstract】 The anti-overturning performance of a super-tall structure consisting of central core tubes,peripheral frames and outtriggers,is studied by shaking talble test.Viscous dampers are introduced to the outriggers for energy dissipation,and thus the reduction efficiency of structral overturning moments are assessed under shaking test.The results are presented for further research on similar super-tall structures.更多还原
