ABSTRACT

A theoretical calculation method for RC bridge column hysteretic model in saline soil environment was proposed. The effects of axial compression ratio and corrosion rate were considered in the test. Based on the failure process of the specimen, a trilinear skeleton curve model was proposed and theoretically calculated. Through the regression analysis of the test results, the unloading stiffness of the specimen in the whole loading process is obtained, and the hysteretic model of RC bridge column is determined. Compared with the test results, it is found that the degree of agreement with the test results is high.

盐渍土环境中钢筋混凝土（RC）桥柱的滞回模型

摘要

提出了一种盐渍土环境下RC桥柱滞回模型的理论计算方法。试验中考虑了轴压比和腐蚀速率的影响。根据试件的破坏过程，提出了三线性骨架曲线模型并进行了理论计算。通过对试验结果的回归分析，得到了试件在整个加载过程中的卸载刚度，确定了RC桥柱的滞回模型。与测试结果相比，发现与测试结果的吻合程度较高。
