| 摘 要： | 采用有限元分析方法,对深圳机场T3航站楼18m预应力梁的施工及变形过程进行数值模拟。考虑到混凝土材料特性随时间变化的影响,同时考虑了如板、次梁、柱的相关影响,将混凝土从筑注开始至完成拆模分为4个阶段。并对施工过程进行模拟,得出各阶段各测点的变形情况。结果表明各阶段模拟结果较为合理,为顺利施工提供依据。

| Abstract: | The construction process and deformation of the 18m-span prestressed beam are analyzed by finite element method.The changes of material properties with times are considered.The influence of related members such as plates,secondary beams beginning and column are analyzed as well.Four stages are divided from concrete pouring beginning to formwork removal.The construction process is simulated,and deformation of the monitored points at each stage is obtained.The simulation result is reasonable for each stage and provides a basis for construction. |
