通过对水下不分散钢筋混凝土柱和普通钢筋混凝土柱在轴向荷载和水平低周反复荷载作用下的对比试验研究,分析了两者抗剪承载力的区别以及影响水下不分散混凝土柱抗剪承载力的因素,如剪跨比、轴压比、配箍率等。试验结果表明,用规范给出的公式计算水下不分散混凝土柱所得的结果与试验值相差较大,通过修正得出了水下不分散混凝土柱抗剪承载力的计算公式,计算结果与试验值较为吻合。
Through the contrast experimental study of underwater undispersed reinforced concrete columns and ordinary reinforced concrete columns under axial load and horizontal low cycle repeated load, the difference between the two shear capacity and the influence of non-dispersed underwater concrete column anti- Shear bearing capacity factors, such as shear span ratio, axial pressure ratio, with hoop rate. The test results show that the formula given by the formula to calculate the underwater non-dispersed concrete column results obtained with a large difference between the experimental value obtained by correction of the underwater non-dispersed concrete column shear capacity of the formula, the calculation results and tests The value is more consistent.
