高层建筑厚板转换层内力分布研究

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。

Analysis of thick plate transition layer for high rise building

The application of thick plate transition layer in high rise building is very widely now.The transition layer has its special distribution rule for the inner forces,and haven't analyzed systematically now.The paper analysis the factors which influenced the distribution of the inner force by the finite element method.The factor discussed here are the thick of the plate,the strength of the material,the decrement of the plate thick in local position,the change of the lower column grid,and the cantilever of the plate.By the analysis,we get some useful conclusions.
