摘　　要：板柱结构体系的整体刚度限制了人们对它的认可与使用,为了研究影响板柱结构整体刚度的主要因素,以及边梁存在随之变化的内部规律,采用有限元软件FEA NX分析4大组不同结构几何参数共计63个板柱结构的受力模型,分析在竖向荷载作用下影响16柱9区格的现浇混凝土板柱计算模型整体刚度因素。在相同因素作用下,对比分析有边梁板柱结构和无边梁板柱结构整体刚度差异。分析结果表明:有边梁板柱结构的最大位移均小于无边梁,边梁对整体刚度的提高有明显作用;边梁的影响作用最大的是板厚,而影响最小的是柱距。The overall stiffness of slab-column structure system limits its acceptance and use. In order to analyze the main factors influencing the slab-column structure overall stiffness, and the inherent law of the edge beam changes accordingly, the finite element software FEA NX was adopted to analyze the structure of four groups which include 63 different geometric parameters, the mechanical model under vertical load impact analysis 16 column 9 area of cast-in-place concrete slab-column calculation model of the whole stiffness factor. Under the action of the same factors, the overall stiffness difference between the edge beam slab-column structure and the edge beam slab column structure is compared and analyzed. The results show that the maximum displacement of the plate column structure of edge beam is smaller than that of the boundless beam, and the edge beam has a significant effect on the improvement of the overall stiffness. The influence of the edge beam is the thickness of the plate, while the influence of the column distance is the least.
