| 摘 要： | 研究了钢筋锈蚀影响下偏心受压构件力学性能和工作机理的变化规律。使用名义屈服强度描述钢筋锈蚀对有效截面积和屈服强度的影响,使用粘结强度降低系数描述粘结强度降低的影响。分别按照大偏压和小偏压的情况,使用有限元方法,建立了锈蚀钢筋混凝土压弯构件的分离式模型,得到了压弯构件承载力、延性、钢筋混凝土共同工作性能等的变化规律。

| Abstract: | Mechanical behavior and working mechanism of reinforced concrete eccentric compression members under the influence of steel bar corrosion is studied in this paper.Nominal yielding strength is established to present the influence of steel bar corrosion on effective section area and yielding strength,and parameter of bonding strength on present influence of reduction of bonding strength.Discrete FEM model for corroded reinforced concrete eccentric compression member is established through finite element method(FEM),and deterioration rule is achieved.A new computation model has been suggested for corroded reinforced concrete eccentric compression member on the assumption of equilibrium under ultimate load.The computation method advised in this paper has been tested in an accelerated corrosion test for reinforced concrete member.The results according to the method matches experiment results very well,which proves the method is feasible. |
