摘要: 通过对5根500MPa级带肋碳素钢筋混凝土简支梁及HRB335、HRB400级钢筋混凝土简支梁各1根的对比试验,观察试件的裂缝、挠度、承载力及破坏形态。对试验结果研究分析表明,500MPa级带肋碳素钢筋混凝土简支梁正截面符合平截面假定;实测挠度符合要求,但大于计算挠度;实测裂缝宽度较大,但小于计算裂缝宽度。

Abstract: Based on the experiments of five simply supported beams with 500MPa ribbed carbon bars,one with HRB335 bars and one with HRB400 bars,it was observed that the crack,deflection,bearing capacity and failure mode of the specimens.The analysis of the experimental results shows that the normal section of the simply supported beam with 500 MPa ribbed carbon bars accords with the plane section assumption;the measured deflection accords with the request but is larger than the calculated deflection;the measured crack width is wide but less than the calculated crack width.
