【摘要】 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。更多还原

【Abstract】 The main idea of the article is to introduce the computable result on deflection and the internal force analyse of the roof which without beams according to the way“Several function program by MBASIC language of finite element method for bending of thin plate”the writer design and realization himself. The characteristics:(1)Take the roof that no beams as the plates which can be changed by the thickness and then you deal with it according to the needs of the realy engineering structure. (2)According to the realy deflection condition of the no beams’s roof,we can suppose the opposite force of the prop be distributed nearby the periphery on the top of the prop’s section. After we compared it with the result got by other way we can know clearly that the explain of the article is trustworthy and it can be used in the design of project.更多还原
