摘要
整体顶升钢平台体系是随着超高层的兴起而发展起来的一种施工技术。以天津周大福金融中心为例,采用理论分析与数值模拟相结合的方法,对整体顶升钢平台体系进行了平台动力特性和风振时程分析,并对分析结果进行了对比,结果表明本文提出的风振分析方法是切实可行的。
The integral lifting steel platform system is a kind of construction technology developed with the rise of super high building.Taking Tianjin Chow Tai Fook Financial Center as an example,this paper combines theoretical analysis with numerical simulation to analyze the dynamic characteristics of the whole lifting steel platform system and the course of its wind-induced vibration.It also compares the results of the analyses.The result shows that the analytical method of wind-induced vibration proposed in this paper is feasible.
