摘要
根据试验结果,以普通钢筋混凝土梁受剪承载力计算公式为基础,采用对比分析方法,研究了混凝土强度、箍筋特征值、预制截面高度与叠合截面高度之比、一期作用跨中弯矩与预制截面极限承载弯矩之比等参数对钢筋混凝土叠合梁受剪承载力的影响规律,提出了集中荷载作用下钢筋混凝土叠合梁受剪承载力的评估方法和对实际工程设计的建议。
In this paper, the effects of the concrete strenght, the characteristic value of stirrups, the depth ratio of precast section to composite section and the moment ratio of first-phase load to ultimate load of precast setion on the shear resistance of reinforced concrete compostite beams subject to concentrated load are investigated. The formulas for evaluating and the suggestion for designing the shear resistance of reinforced concrete composite beams sujbect to concentrated load are proposed.
