| 摘 要： | 复合砂浆钢筋网薄层加固是一种有效的新型加固方法,能够显著地提高钢筋混凝土梁的抗剪承载力以及抗裂性能.在6根复合砂浆钢筋网加固RC简支梁和1根对比梁的试验基础上,研究了加固梁各种参数对梁极限抗剪承载力的影响,并分析对比了各组加固梁的破坏形态、斜裂缝、荷载-跨中挠度曲线的变化规律.给出了复合砂浆钢筋网加固RC梁的极限抗剪承载力计算公式,计算结果与试验结果吻合较好.

| Abstract: | Ferrocement mortar technology is an efficient method to reinforce RC beams,which can obviously increase the shear load-carrying capacity and crack-resisting behavior.Based on experimental study of 6 RC beams strengthened with ferrocement mortar and one comparative RC beam,the influence of kinds of parameters on the ultimate shear load-carrying capacity was analyzed.Subsequently,the rules of failure forms,diagonal crack width and load-deflection curves of strengthened beam were analyzed.A computational expression of the shear load-bearing capacity of RC beam strengthened with ferrocement mortar is proposed.The calculated results are fit together well with the experimental results. |
