| 摘 要： | 为推广HRB500级钢筋,并为其在《混凝土结构设计规范》局部或全面修订时列入提供依据,需对HRB500级钢筋混凝土构件性能进行试验研究。在4根HRB500级钢筋混凝土偏心受压柱试验的基础上,分析了HRB500级钢筋和高强混凝土匹配下的偏心受压柱的破坏形态、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柱基本一致。但其混凝土强度较高时正截面承载力较理论计算结果偏小。

| Abstract: | In order to generalize HRB500 reinforcement and provide warrant for the redaction of Code for Design of Concrete Structures,the experiment researches should be done on the main characteristic of HRB500 reinforcement concrete members.The results of experimental study of 4 HRB500 reinforcement concrete columns under monotonous eccentric compression are summarized.Based on 4 tests,the typical features of deflection,the failing forms and the compressive behavior of columns are analyzed.It is shown that the fail... |
