高层建筑结构施工力学分析

Construction mechanics analysis in tall buildings

通常高层结构设计是以建造好结构在使用荷载下的计算模型为依据。然而这是同结构在实际施工过程产生的力学状态有差异的。为此本文将采用超级有限元－有限元耦合法对高层结构进行施工模拟分析，按照施工顺序及施工时的实际情况进行力学分析，从而对保证结构建造全过程的可靠性和安全性，指导选用合理的施工方案。

Usually, tall buildings are designed on the basis of the whole structural compute models under load. However, there are difference in reality construction course of constructures and mechanics conditions. In this paper, the construal analysis of the tall buildings is done by the use of supper finite elements finite elements combinative method according to the construction order and actual situation. Thus, applied to the tall buildings, the method will have theoretical significance and current significance so as to guarantee reliability and safety in the constructural course.
