THE RESEARCH ON DIAGONAL CRACKING OF REINFORCED CONCRETE BEAMS WITH HIGH STRENGTH REBARS BASED ON MODEL TEST

摘要: 通过对配置高强度钢筋的混凝土梁在集中荷载作用下的受剪试验,从构件挠度、斜裂缝宽度及箍筋应变的角度分析其斜向开裂特征规律,研究混凝土强度、剪跨比、配箍率、截面尺寸及截面形状对构件斜向开裂荷载的影响规律,并对斜向开裂荷载的理论计算方法进行探讨。研究结果表明:混凝土强度、剪跨比、截面尺寸是配置高强钢筋混凝土梁斜向开裂荷载的主要影响因素,并由此提出斜向开裂荷载的建议计算公式,为工程应用中斜向开裂荷载计算以及高强钢筋的快速推广使用提供参考依据。

Abstract: An experiment on shear of reinforced concrete beams with high strength rebars was carried out. According to observing the deflection，diagonal crack width and strain of stirrups，the diagonal cracking rules were analyzed. The effects of concrete strength，shear span ratio，ratio of stirrup，section size and section shape on diagonal cracking loads were studied and the calculation method of the diagonal cracking loads was discussed. The results showed that concrete strength，shear span ratio and section size were the major factors for the diagonal cracking loads of reinforced concrete beams with high strength rebars. Meanwhile，the calculation formula of the diagonal cracking loads was suggested，which provided a basis for calculation of the diagonal cracking loads and promoting the use of HRBF500 high strength rebars in practical engineering.
