摘要
采用SAP2000有限元分析软件对某工程无梁楼盖体系地下室关键柱破损事故进行分析。首先介绍了相关项目背景;然后采用SAP2000有限元分析软件进行建模,合理选取计算模型和边界条件,并分几种不同的荷载工况进行数值模拟;最后,通过对数值计算结果的分析,得出柱在不同荷载工况作用下的受力性能及相关分析方法。相关研究成果可供同类工程事故分析及加固设计参考借鉴。
Analysis on failure of key columns of a flat plate basement floor is carried out based on the finite element software SAP2000. First,the background of the accident is introduced. Then,the modeling is established by SAP2000,including selection of numerical model and treatment of the boundary conditions. Numerical simulations subjected to different loading conditions are then carried out. Finally,the performances of the failure columns as well as corresponding analysis methods are presented. The research results obtained are of engineering significance for similar engineering accident analysis as well as reinforcement design.
