梁尺寸对宽扁梁楼盖结构的影响

Influence of the beam size to the structure of the flat beam floors

通过对几组变参数的3×3跨钢筋混凝土宽扁梁楼盖在竖向荷载作用下弹性阶段的受力性能进行有限元分析,主要讨论了梁宽和梁高对结构内力的影响,通过分析认为梁高对提高结构受力性能的贡献最大,但受到空间因素的制约,梁高不能无限制加大。

Through the finite element analysis of the mechanical behavior of 3 × 3 span reinforced concrete flat beam floors with the variable parameter at the elastic stage under the vertical loads effect, the paper mainly discusses the influence of the beam width and the beam height to the structural internal force, and the beam height makes the most important contribution to the performance improvement of the structural internal force by the analysis, but the beam height can not be illimitably increased because of the restriction of the space factor.
