摘　　要：通过钢骨混凝土桥墩在侧向集中力作用下的静力抗剪试验,研究了钢骨混凝土桥墩的斜截面抗剪承载力的影响因素,分别用叠加法和考虑抗剪刚度影响的桁架拱模型提出了2种钢骨混凝土桥墩的斜截面抗剪承载力计算公式,与试验结果吻合较好。Experimental studies on the static shear performance of steel reinforced concrete bridge piers,the factors that effect shear resistance of the oblique sections were investigated. There are two shear resistance formulas have been put forward. One is superposition method,the other is truss-arch model which considers shear stiffness. These methods agree with the results of our experiment well.
