| 摘 要： | 通过对5根500MPa级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,观察了试件的变形特征及破坏形态.对试验结果进行的研究分析表明,500MPa级钢筋混凝土简支梁的变形特征与普通的HRB335,HRB400级钢筋混凝土简支梁基本相同,在正常使用状态下实测的挠度大于计算挠度,建议现行设计规范应考虑这类钢筋的受力特性,并在应用条件上作出规定.

| Abstract: | Based on the experiments of five simply supported beams with 500MPa bars, one with HRB335 bars and one with HRB400 bars, they are observed that the deformation characteristic and failure mode. The analysis of the experiment results shows that the deformation characteristic of the simply supported beam with 500MPa bars is almost the same as the simply supported beam with HRB335 bars and HRB400 bars. Under the state of serviceability the measured deflection is more than the calculated deflection. It is proposed that this rebar behavior be included in the design code with application condition. |
