| 摘 要： | 核筒悬挂建筑结构是一种新型的高层建筑结构体系,其风致响应的研究很少.模拟了B类地貌下的风速时程,并转化为作用在结构上的风荷载时程;利用有限元软件ANSYS建立了结构计算模型,进行了结构水平顺风向风振响应分析,并与悬挂非减振结构进行比较,给出了阻尼器参数优化结果.分析结果表明,在水平顺风向风荷载作用下,核筒悬挂减振结构与...

| Abstract: | The Core-tube suspended structure is a novel kind of high-rise structural systems,while its wind-induced responses have not been studied systematically.The wind speed time-history in B class landscape is simulated.And then the wind speed time-history is transformed into wind load time-history acting on the building structure.The calculation model of a vibration-absorption suspended building is built with the finite element method software ANSYS.Then the wind-induced responses are calculated,which are compar... |
