摘要
通过对2根对比梁和4根加固的钢筋混凝土梁的抗剪试验,研究不同剪跨比和不同受力方式下的RC梁采用钢纤维水泥砂浆钢筋网加固后的抗剪性能.主要分析了各组对比梁及加固试验梁的破坏形态、斜裂缝、挠度、应变的变化规律.依据实验结果,提出了钢纤维水泥砂浆钢筋网加固RC梁的抗剪承载力计算公式,计算结果与试验结果吻合较好,可为实际加固工程设计提供理论参考.
Experimental research on the shear test behavior of different shear-span ratios and different stress modes was carried out through the experimental research on two general beams and four RC beams strengthened with steel fiber ferrocement mortar. The regulation for the change of the mode of failure, diagonal cracks, deflection and strain was analyzed in the experiment. According to the test results, the computational formula of the shear load capacity of RC beams strengthened with the steel fiber ferrocement mortar was established. The calculation results fit well with the experimental results, which provides a theoretical reference for actual engineering designs.
