高层建筑厚板转换层的使用日益广泛，其内力分布有特殊的规律．对此，目前尚无系统的分析讨论．本文应用有限元分析的方法，对转换层厚板的板厚、材料强度、局部板厚减薄处理、改变下部柱网尺寸与设置板的悬挑等诸多影响转换层厚板内力的因素作系统的分析研究，并从中得到了一些有益的结论． The use of thick slab conversion layers in high-rise buildings is increasingly widespread and there are special rules for the distribution of internal forces. In this regard, there is no systematic analysis and discussion. In this paper, the finite element analysis method is used to make a system of factors affecting the internal force of the conversion layer slab, such as the thickness of the conversion layer slab, the material strength, the partial thickness reduction, the change of the size of the lower pillar net, and the overhanging of the setting panel. Analytical research, and got some useful conclusions from it.
