摘要
根据反复荷载下人工气候环境加速钢筋锈蚀的钢筋混凝土压弯构件力学性能的试验结果,提出了反复荷载作用下恢复力模型中与钢筋锈蚀率相关的特征参数计算公式,建立了锈蚀钢筋混凝土压弯构件的退化双折线恢复力模型,并与参考文献试验结果进行了对比,结果表明本研究建立的恢复力模型具有一定的适用性。
According to the experimental study on mechanical behavior of corroded reinforced concrete columns for axial load and moment under cyclic loading,the formula of model parameters related to steel corrosion rate are proposed and deteriorating double lines restoring force model of corroded reinforced concrete columns for axial load and moment is established.Compared with experimental results in another literature,it is founded that the restoring force model established is of a certain degree of adaptability.
