通过对2根碳纤维复材筋珊瑚骨料混凝土梁和2根碳纤维复材筋普通混凝土梁的受剪对比试验,对碳纤维复材筋混凝土梁破坏形态、裂缝开展等情况进行观察,探讨不同混凝土种类、强度下的梁破坏形态;分析不同配箍率和不同剪跨比对梁开裂荷载、极限承载力和挠度的影响规律;通过试验结果与理论计算的承载力、裂缝宽度等对比,验证了GB 50608—2010《纤维增强复合材料建设工程应用技术规范》中规定计算方法对碳纤维复材筋珊瑚骨料混凝土梁抗剪验算的适用性。
By comparing the shear tests of two CFRP-reinforced concrete cobwebs and two CFRP-normal concrete beams, the damage morphology and fracture development of CFRP reinforced concrete beams were observed and the effects of different concrete types And the strength of the beam failure morphology; analysis of different stirrup ratio and different shear-span ratio of beam cracking load, ultimate bearing capacity and deflection of the law; through the test results and the theoretical calculation of bearing capacity, crack width and so on, verify the GB 50608-2010 “Fiber Reinforced Composites Construction Project Application Technical Specification” provides the calculation method of carbon fiber reinforced composite materials tendons tendons shear test applicability.
