| 摘要: |
| 进行了钢筋混凝土（RC）原梁、钢筋钢丝网砂浆（SWM）加固RC梁和钢筋网砂浆(SM)加固RC梁的抗剪试验研究.结果表明：相对于SM加固法，SWM加固法能大幅度提高加固梁的抗剪承载力；即使在钢丝网用量很少的情况下(施工方便)，加固梁仍具有良好的裂缝控制能力和相对较大的变形能力.同时，给出了加固梁的抗剪承载力和斜裂缝宽度的计算公式，其计算结果与试验结果基本吻合. |

| Abstract: |
| Steel bar/wire mesh mortar(SWM) reinforced concrete(RC)beams, steel bar mortar(SM) RC beams, and controll RC beams were produced for comparison study experimentally. Results indicate that SWM can significantly enhance the shear capacity of reinforced beams. Even though under low reinforcement ratios of wire mesh, the SWM reinforced beams still have good anti cracking property and relatively larger deformation capacity. Calculation formula for predicting the shear capacity and diagonal crack width of reinforced beams is also provided and show a basic agreement with the tested results. |
