上下肋对蜂窝形钢筋混凝土空腹夹层板挠度影响分析

Influence of Upper and Lower Ribs on the Deflection of the Honeycomb Shape Reinforced Concrete Open-web Sandwich Plate

为了研究蜂窝形钢筋混凝土空腹夹层板上下肋对其挠度的影响,运用有限元软件Midas建立了某大跨度楼盖模型,计算出不同上下肋尺寸下楼盖的挠度,对挠度曲线进行拟合,得到了挠度与肋高、肋宽的关系式。研究结果表明,蜂窝形钢筋混凝土空腹夹层板的挠度与肋高、肋宽均呈指数关系,且随着肋高和肋宽的增大而减小。肋高比肋宽对结构的挠度影响更显著。

In order to study the honeycomb reinforced concrete open-web Sandwich Plate under the rib effect on the deflection,the finite element software Midas was used to build a large span floor model,on the floor under the rib size under the deflection fitting of the deflection curve was calculated,the relationship between the deflection and the fin height,fin width was obtained. The results show that the deflection of the honeycomb reinforced concrete hollow sandwich plate has an exponential relationship with the rib height and the rib width,and decreases with the increase of the rib height and the rib width. The effect of rib width on the deflection of the structure is more significant.
