摘　　要：研究了局部区段内锈蚀钢筋暴露、混凝土保护层剥落的钢筋混凝土柱的承载力问题。考虑局部区段内不同钢筋锈蚀率、柱两侧钢筋均暴露的情形,通过理论分析,提出了一种计算局部区段内钢筋锈蚀情况下的偏心受压柱的承载力简化计算模型,并通过实验验证了模型的可行性。The load capacity of reinforced concrete（RC） column with partial length corrosion is theoretically studied,where the exposure of the longitudinal bar,delaminating of concrete cover and loss of the bond within this partial length are considered.Simplify analytical model about the load capacity of RC column with partial length corrosion under eccentricity load is proposed through the theoretical analysis,and the feasibility of the proposed model is verified by the experiment results.
