本文旨在介绍采用作者自行设计的“薄板弯曲有限元法 MBASIC 语言多功能通用源程序”对无梁楼盖进行变形和内力分析的计算结果。其特点是:(1)根据工程结构的需要将无梁楼盖作为变厚度的板处理。(2)根据无梁楼盖的实际变形情况,假定支柱反力集中分布在柱顶截面周边附近。通过与其它方法计算结果比较,可以看出本文解答的精确度是可靠的,可以应用工程设计。
The purpose of this paper is to introduce the calculation results of the deformation and internal force analysis of beamless floor slabs using the MBASIC language multi-purpose universal source program of the thin plate bending finite element method designed by the author. Its characteristics are: (1) The beamless floor cover is treated as a variable thickness plate according to the needs of the engineering structure. (2) According to the actual deformation of the beamless floor, it is assumed that the pillar reaction force is concentrated near the perimeter of the column top section. Comparing with the calculation results of other methods, it can be seen that the accuracy of the solution in this paper is reliable and the engineering design can be applied.
