摘要
传统的结构设计理论只针对使用阶段的结构在不同荷载工况及其组合作用下的效应进行分析,以此来保证建筑结构具有一定的安全性和适用性,实际上,结构的自重等恒荷载是在施工过程中随着施工步的推进逐步施加在结构上的。文中以深圳证券交易所广场工程为背景,采用ANSYS中的单元生死技术按照拟定的施工方案对结构施工进行全过程跟踪分析,并与一次成型下结构位移变化情况进行对比,以此说明研究裙楼巨形悬挑钢桁架结构成型过程中位移变化及位移控制的必要性。
In order to guarantee structure to be the safe and applicable, the theory of the traditional structural design just analyse the effects at application stage of structure in different load eases and composite action. In fact, constant load of the structure, such as self-weight is put on structure step-by-step with the advance of the construction step. This paper take the project of Shenzhen Stock Exchange Plaza as background and adopt element birth and death technology provided by ANSYS to trace and analyze the whole construction process, compared with the traditional design to account for the necessity of studying displacement and displacement control.
