摘要
根据受腐蚀钢筋混凝土偏心受压试件的试验结果,提出了受腐蚀钢筋混凝土构件的恢复力模型及其骨架曲线的确定方法。研究表明,对于受腐蚀的钢筋混凝土结构,尽管由于腐蚀作用钢筋与混凝土的滑移不能再使构件的变形保持平截面,但对根据平截面假定计算的荷载-变形曲线进行修正,可获得与试验符合的结果。受腐蚀钢筋混凝土构件的恢复力模型仍可采用现有的恢复力模型。
Methods to determine the skeleton curve and restoring model of corroded reinforced concrete elements are presented. Based on experimental results, it is shown that the load-deformation curve calculated using the linear plane assumption, with modification, may still be used as the skeleton curve of corroded reinforced concrete elements. Good agreement between the calculated curve and the test result is obtained.
