Numerical Simulation Analysis on Flexural Performance of High-strength Concrete Beams with HRB600 Steel Bars

为研究HRB600级钢筋高强混凝土梁的受弯性能,在试验基础上,利用ABAQUS软件进行了非线性有限元分析,深化研究了混凝土强度、钢筋强度、配筋率设计参数对试件受弯性能的影响。结果表明:随着混凝土强度的提高,试件承载力有相应提高,但不明显;随着配筋率的提高,试件的承载力有明显提高;随着纵筋强度的提高,试件的承载力有相应提高。

In order to study the flexural performance of High-strength concrete beams with HRB600 steel bars,on the basis of experiments,a nonlinear finite element analysis was carried out with ABAQUS software,and the influence of the design parameters of concrete strength,steel bar strength and reinforcement ratio on the bending performance of specimens were deeply.The results show that:with the increase of the concrete strength,the bearing capacity of the specimen is improved,but not obvious;with the increase of the reinforcement ratio,the bearing capacity of the specimen is significantly improved;with the increase of the longitudinal reinforcement strength,the bearing capacity of the specimen is correspondingly improved.
