摘要
通过对沈阳市府恒隆广场350m高塔楼顶部的皇冠钢结构施工过程进行模拟分析,简要介绍了复杂钢结构施工过程模拟分析的方法、步骤、施工阶段划分的原则、条件假定、临时支撑的反力分析、加固结构的承载力分析以及后装缺口的变形控制等,通过施工阶段模拟分析的方法,来确定施工方案、优化施工顺序,确保施工方案的可行性、科学性,同时避免盲目施工所带来的结构安全和质量隐患。
Through the simulation analysis of the construction process of steel crown structure at the top of 350-meter-high building of Hang Lung Plaza in Shenyang,this paper briefly introduced the simulation analysis of the construction process of complex steel structure in terms of the approaches, the steps,the principles of the construction stage division,the assumption of conditions,the reaction force analysis of temporary supports,the bearing capacity analysis of the reinforced structure,as well as the analysis of the deformation control of the afterloading gaps and so on.The construction scheme was identified and the construction sequence was optimized through simulation analysis of construction process,thus the feasibility and scientificity of the construction scheme was confirmed which could avoid the quality problems caused by blind construction.
