摘　　要：大型空间结构施工方法的多样化和复杂化,造成施工阶段结构内力分布的复杂性和最终成型结构受力可变性。为确保工程建设安全、经济、顺利地进行,要求在结构建造过程中按照客观条件确定经济合理的施工顺序,有必要针对大型空间钢结构进行施工全过程模拟分析以了解结构在施工阶段的力学特性,同时研究结构施工过程中诸如安装方案安全性等一系列相关问题。Diverse and complex of the construction method of large space structures, resulting in the construction phase structure of the internal force distribution complexity and end-forming structure of force variability. To ensure the construction projects safety ,economic,and successfully carried out that the construction process need according to the objective conditions to determine the economic and reasonable construction sequence, it is necessary for large space steel structure use the whole construction process simulation analysis which is in order to understand the mechanical properties of the structure during the construction phase , in the meantime consider such as installation programs and security related issues during the structure construction.

关 键 词：大跨度空间结构 钢结构 结构内力
