The Deformation Analysis and Control of Large Steel Structures Based on Non-slide Construction Site

摘要

The layered construction technique is the common method of large steel structures in the non-slide construction. In process of the former three-tier construction, the structure is prone to forming large deformation because of great span, large weight of interlayer equipments and other various factors. In this article, to obtain high dimensional accuracy and good deformation control data, the positions of temporary support points of the 3M201 that is a module of large steel structure in a project are optimized successfully with the ANSYS optimization of finite element.
