对锈蚀钢筋混凝土柱的抗震性能进行了试验研究，分析锈蚀试件的破坏过程和破坏特点，重点研究了柱纵筋锈蚀率和轴压比对锈蚀钢筋混凝土柱受力性能的影响。在试验研究基础上，对反复荷载作用下钢筋混凝土柱的分析模型进行修正，建立了锈蚀钢筋混凝土柱的压-剪-弯交互作用分析模型，应用改进斜压场理论、传统截面分析法对锈蚀钢筋混凝土柱的受剪机理、受弯机理进行分析，通过锈蚀压弯构件轴向应变的变形协调将受弯模型和受剪模型结合，最终计算获得锈蚀钢筋混凝土柱的承载能力和极限变形，并通过12根锈蚀钢筋混凝土柱的试验结果对建议分析模型进行了验证。研究结果表明：锈蚀钢筋混凝土柱承载能力试验值与计算值之比的平均值为1．107，方差0．010，吻合较好；锈蚀试件按建议分析模型计算得到的极限变形与试验数据接近，平均值为0．873，方差0．051。因此，建议模型可分析水平反复荷载作用下锈蚀钢筋混凝土柱的极限变形和承载能力。

英文摘要：

The seismic behavior of corroded reinforced concrete columns was experimentally studied under reversed cyclic loading. The failure process and failure characteristics of corroded specimens are analyzed. The experimental study was conducted that focused on the effect of corrosion ratio and axial compression ratio on the behavior of cor- roded reinforced concrete columns. Based on experimental study, an analytical model of corroded reinforced con- crete columns under the axial-shear-flexure interaction action is established by modifying the mechanical model of reinforced concrete columns under reversed cyclic loading. The section analysis techniques are employed for model- ing the flexure mechanism, and the simplified modified compression field theory is implemented for modeling the shear behavior of elements. Average centroidal strains and average concrete compression strains derived from the flexural model are implemented in the shear model and used to calculate shear deformation and concrete strength degradation. The approach is employed for the estimation of the load capacity and the ultimate deformation of corro- ded reinforced concrete columns previously tested. Furthermore, the suggested analytical model was verified using 12 test data of corroded reinforced concrete columns. Good agreements between test result and predicted 10ad ca- pacity was achieved with average ratio of test values to predicted values of 1. 017, and the corresponding variance is0. 010. The average ratios of test result to ultimate deformation predicted was 0. 873, and the corresponding vari- ance is 0.05 i. Thus, the suggested axial-shear-flexure interaction model can be served as the analysis tools of ana- lyzing the behavior of corroded reinforced concrete columns.
