| 摘 要： | 通过１２根钢筋混凝土迭合梁在多点等代均布荷载作用下斜截面受力性能的试验，研究了预制截面与迭合截面高度比和一期荷载作用跨中弯矩与预制截面极限承载弯矩之比对钢筋混凝土梁斜截面抗裂性能的影响规律。在原钢筋混凝土梁斜截面抗裂计算理论模式基础上，提出了均布荷载作用下钢筋混凝土迭合梁斜截面抗裂计算方法。

| Abstract: | Tests were carried out to study the shear behavior of reinforced concrete composite beams subject to two-phase uniformly distributed load.The test program included 12 rectangular reinforced concrete composite beams,the major parameters of the study were the depth ratio of precast section to composite section and the moment ratio of first-phase load to ultimate load of precast section.Based on the test results,the effects of the studied parameters on the shear-cracking resistance of reinforced concrete composite beams are analyzed.A method for calculating the shear-cracking resistance of reinforced concrete composite beams,which link up with that of the reinforced concrete beams,is proposed. |
