现浇井字梁楼盖支承条件的有限元分析

Supporting conditions of finite element analysis and engineering applicationon cast-in-situ concrete groined slab

随着我国建筑结构多样性及复杂性的需求日益明显,混凝土井式梁楼盖结构是一种具有良好的结构性能和综合经济效益的结构形式。本文应用有限元软件AN-SYS对梁周边处为柱(即环梁)支承时,在不同布置条件下对井式梁结构受力性能进行分析,得到该体系合理的传力关系和受力关系规律。

With the improvement of our national economy,structural diversity and the needs of complexity obvious increasingly,the concrete groined slab is the structure with good performance and overall economic benefits.This paper use finite element software ANSYS to analyze and study the mechanical properties in different arrangements when supported column（ie.rim beaming） at four sides,we can get a reasonable relationship of loading and forcing.
