随着建筑结构形式日趋复杂多样,有限元软件在建筑结构设计和验算中的应用越来越普遍,文中介绍了有限元算法和传统算法的原理,通过建立4个梁板计算模型,对比分析两种算法的结果差异,并查找结果差异原因,为两种分析方法在验算相同结构特别是施工阶段验算时的适用条件提出建议。
With the increasingly complex and diversified architectural forms, the application of finite element software in the design and verification of building structures is becoming more and more common. The principles of finite element method and traditional algorithms are introduced in this paper. By establishing four beam plate calculation models and comparing two The difference between the results of the two kinds of algorithms and the reasons for the differences of the results are discussed. Suggestions are made for the applicability of the two methods in checking the same structure, especially in the construction phase.
