武汉天河机场T3航站楼钢屋盖错层提升技术模拟研究
|
摘要
基于武汉天河机场T3航站楼钢屋盖工程,研究屋盖施工错层提升技术。利用MIDAS建立桁架模型,对提升过程中钢桁架的内力和变形进行分析;根据模型所计算的吊点反力结果,设计相应的提升架;并利用ANSYS及SAP2000建立提升架分析模型,对提升荷载条件下提升架的变形和内力进行分析。结果表明,本工程所采用的错层提升技术安全可行。
Based on the steel roof structure project of Wuhan Tianhe Airport T3 terminal building,the staggered lifting construction technology was studied. The truss model was established by MIDAS,and the internal force and deformation were tested. According to the calculation results of the lifting points of the model,the corresponding lifting frame was selected, and the improved frame analysis model was established by ANSYS and SAP2000,so the internal force and deformation of the lifting frame were tested. The results showed that the staggered lifting technology was safe and feasible.
