(华北水利水电学院土木系 郑州 450045)[提要] 根据试验结果,研究了在均布荷载作用下的钢筋混凝土叠合梁斜截面承载力受预制截面高度与叠合截面高度之比和一期荷载作用中跨中弯矩与预制截面极限承载弯矩之比等叠合参数的影响规律,并对其计算方法进行了分析讨论。
[关键词] 钢筋混凝土 叠合梁 均布荷载 斜截面承载力On the basis of test results, the effects of the composite coefficients, such as the depth ratio of precast section to composite section and the moment ratio of first-phase load to ultimate resistance load of precast section, on the shear resistance of reinforced concrete composite beams subject to two-phase uniformly distributed load are studied, Meanwhile, the calculation method is analyzed and proposed.
Keywords: reinforced concrete; composite beam; uniformly distributed load; shear resistance
