两种柱帽形式无梁楼盖有限元分析对比

Finite Element Analysis of Two Types of Column-cap Flat Slab

上反柱帽无梁楼盖相比传统柱帽无梁楼盖具备减少层高、提高空间利用率从而降低成本的优点,近年来得到越来越多的应用。采用有限元分析软件对上反柱帽和传统柱帽两种无梁楼盖的局部模型和整体模型,进行了静载作用下的弹塑性分析对比。有限元分析结果反应了这两种楼盖的承载能力和延性等力学差别,可供类似工程设计参考。

Compared with traditional flat slab, the one with reverse column-cap has advantage of less space occupation, lower story height and economic efficiency.Therefore it has been applied in more projects recently.In this paper, the elastic-plastic finite element analysis under static loading was conducted on both traditional and reverse cap fiat slab.The results show the difference of load capacity and ductility between these two types of flat slab.
