Corrosion of steel reinforcement has been specified as the impairment mechanism of reinforced concrete buildings, which severely affects the safety and integrity of buildings. The corrosion of the embedded reinforcing steel in concrete is a significant trouble facing civil engineers nowadays, which initiates 80% of the reinforced concrete buildings impairment. This paper detects the outcomes of an experimental investigation on the mechanical performance of five squared steel reinforced columns which have been damaged by corrosion of the steel rebar. Small scale square reinforced concrete columns with a rectangular cross-section of bh=150mm150mm and 500 mm in height were adopted. Various degrees of steel reinforcement mass loss (corrosion damage) ranged between 8%, to 15 % were formed in the columns by using an accelerated galvanostatic corrosion method. The uniaxial compression test was carrying out for harmed columns up to failure. Based on the experimental outcomes, the corrosion damage had substantially reduced the performance of columns. The deterioration of the load capacity of corroded columns was 13.4%,24.6%,22.5% and 45.34% at level of corrosion damage of 8% and 15% respectively for longitudinal bars only and for longitudinal and ties reinforcement. The reduction of the axial and lateral deformation of corroded columns ranged between 7.1% to 70.22% and for corrosion level ranged from 8% to 15%, respectively. Likewise, the failure mode for corroded columns had been adversely affected by corrosion.

钢筋腐蚀已被指定为钢筋混凝土建筑物的损伤机制，严重影响建筑物的安全和完整性。混凝土中预埋钢筋的腐蚀是当今土木工程师面临的一大难题，它引发了80%的钢筋混凝土建筑损伤。本文检测了对因钢筋腐蚀而损坏的五个方形钢筋柱的力学性能的试验研究结果。采用矩形截面bh=150mm150mm、高500mm的小型方形钢筋混凝土柱。不同程度的钢筋质量损失（腐蚀破坏）在8%之间，通过使用加速恒电流腐蚀方法在柱中形成至 15%。对损坏的柱子进行单轴压缩试验直至失效。根据实验结果，腐蚀损坏大大降低了色谱柱的性能。在腐蚀损伤水平为8%和15%的情况下，仅纵筋和纵筋和拉杆钢筋锈蚀柱的承载能力恶化分别为13.4%、24.6%、22.5%和45.34%。腐蚀柱的轴向和横向变形的减少范围在 7.1% 到 70.22% 之间，腐蚀水平的减少范围分别为 8% 到 15%。同样，腐蚀柱的失效模式也受到腐蚀的不利影响。根据实验结果，腐蚀损坏大大降低了色谱柱的性能。在腐蚀损伤水平为8%和15%的情况下，仅纵筋和纵筋和拉杆钢筋锈蚀柱的承载能力恶化分别为13.4%、24.6%、22.5%和45.34%。腐蚀柱的轴向和横向变形的减少范围在 7.1% 到 70.22% 之间，腐蚀水平的减少范围分别为 8% 到 15%。同样，腐蚀柱的失效模式也受到腐蚀的不利影响。根据实验结果，腐蚀损坏大大降低了色谱柱的性能。在腐蚀损伤水平为8%和15%的情况下，仅纵筋和纵筋和拉杆钢筋锈蚀柱的承载能力恶化分别为13.4%、24.6%、22.5%和45.34%。腐蚀柱的轴向和横向变形的减少范围在 7.1% 到 70.22% 之间，腐蚀水平的减少范围分别为 8% 到 15%。同样，腐蚀柱的失效模式也受到腐蚀的不利影响。34% 在腐蚀损伤水平分别为 8% 和 15% 的情况下，仅纵向钢筋和纵向钢筋和拉杆钢筋。腐蚀柱的轴向和横向变形的减少范围在 7.1% 到 70.22% 之间，腐蚀水平的减少范围分别为 8% 到 15%。同样，腐蚀柱的失效模式也受到腐蚀的不利影响。34% 在腐蚀损伤水平分别为 8% 和 15% 的情况下，仅纵向钢筋和纵向钢筋和拉杆钢筋。腐蚀柱的轴向和横向变形的减少范围在 7.1% 到 70.22% 之间，腐蚀水平的减少范围分别为 8% 到 15%。同样，腐蚀柱的失效模式也受到腐蚀的不利影响。
