【摘要】 在3根HRB500级钢筋混凝土连续梁受弯试验的基础上,分析了HRB500级钢筋和高强混凝土匹配下的梁的破坏形态、变形特点和承载性能。结果表明:其破坏特征、挠曲模式及截面应变分布与普通高强混凝土梁基本一致。梁裂缝宽度较规范计算的结果小,其塑性调幅能力不明显。更多还原

【Abstract】 This paper analysed the failure modes,deformation characteristics,load carrying capacities and plastic amplitude modulation capacities of 3 continuous beams set up with grade HRB500 reinforcement and high strength concrete based on a bending experiment.The result indicated that the failure modes,flexural modes and the section’s strain distribution of the 3 beams are almost consistent with the common RC beams.The beams’ crack width are smaller than the results calculated by the code.The plastic amplitude modulation capacities are insufficient.更多还原
