通过 12根碳纤维布补强加固钢筋混凝土梁的试验 ,重点研究碳纤维布对梁抗剪承载力的影响和作用。主要试验参数有 :碳纤维布的宽度和间距、碳纤维布的粘贴层数、梁的剪跨比、配箍率和混凝土强度。试验研究表明 ,碳纤维布可以明显地提高钢筋混凝土梁的抗剪承载力 ,并改善构件的变形性能 ,增强构件的变形能力。最后 ,提出了一个简化的碳纤维布提高钢筋混凝土梁受剪承载力的设计计算公式。 Through the experiment of reinforcing and reinforcing RC beams with 12 carbon fiber cloths, the effect and effect of CFRP sheets on the shear strength of beams are emphasized. The main test parameters are: the width and spacing of carbon fiber cloth, the number of layers of carbon fiber cloth paste, beam shear span ratio, stirrup ratio and concrete strength. Experimental studies show that carbon fiber cloth can significantly improve the shear capacity of RC beams and improve the deformation performance of members and enhance the deformation capacity of the members. Finally, a simplified formula for calculating the shear capacity of reinforced concrete beams with carbon fiber sheets is proposed.
