摘要
结合实际工程,借助通用有限元软件,分别给出两种不同建模方法下结构拆撑前后的应力变化情况,并与实测应变观测数据对比,阐述施工模拟分析的实用性和准确性,找出结构在卸载中薄弱环节,并提出相应施工建议,为今后类似工程施工提供参考。
Combined with the actual engineering,two different kinds of modeling method were given in this paper to calculate the variation of stress before and after supporting by the general finite element software. Also, comparing the calculated results and the measured strain,expounding the practicability and accuracy of construction simulation analysis to identify structural weaknesses during the unloading. At last,appropriate construction recommendations were made to provide reference for future similar projects.
