摘要
设计了组合试验装置和系列弯剪扭受力组合,完成了7根钢筋混凝土矩形截面构件的弯剪扭组合试验研究。基于前苏联学者提出的钢筋混凝土构件斜截面极限强度理论,提出了钢筋混凝土构件弯剪扭组合受力强度计算公式,并将本文理论模型计算数据与本文及已有的试验数据作比较,发现结果均基本一致。
The experimental equipment and a serial of force combinations are designed, and seven pieces of reinforced concrete members are experimented with different forces combination of bending, shear and torsion. Here, the traditional ultimate strength model of inclined sections is modified, and the failure strength of reinforced concrete members under combined forces is calculated. The theoretical results are compared with the experimental results of seven RC members, as well as other experimental results, which shows a good coordination.
