钢筋陶瓷混凝土黏结性能及梁受弯性能实验研究
Experimental Study on Bond Behavior Between Steel Bars and Ceramic Concrete and Flexural Behavior of Ceramic Concrete Beam
摘要
Abstract
To apply ceramic concrete to engineering structural components,the bond behavior of steel bars and ceramic concrete was studied through a central pull-out test,and the bond-slip constitutive model of ceramic concrete and the prediction formula of ultimate bond strength were given.The flexural behavior of reinforced ceramic concrete beams was studied through four-point bending test,and the flexural performance was studied from the aspects of bearing capacity,deflection,longitudinal bar strain,average crack spacing and maximum crack width.The results show that the bond behavior of ceramic concrete is weaker than that of ordinary concrete,the ultimate bond strength is close to that of ordinary concrete,the rate of descent is greater than that of ordinary concrete,and the residual bond strength is lower than that of ordinary concrete.The bending process and bearing capacity of reinforced ceramic concrete beams are similar to those of ordinary concrete beams,but the average crack spacing is greater than that of ordinary concrete,and the calculation of the maximum crack width still agrees with Chinese concrete design code.关键词
