| 摘 要： | 基于锈蚀钢筋混凝土大偏心压弯构件承载能力退化的性能,考虑锈胀力引起的钢筋周围双向应力状态,建立了锈蚀开裂前钢筋混凝土大偏心压弯构件承载力计算模型;考虑截面锈胀后几何尺寸损失,又建立了锈蚀开裂后钢筋混凝土大偏心压弯构件承载力计算模型.试验结果显示:试验值与计算值符合较好,模型可用于锈蚀钢筋混凝土大偏心压弯构件承载力计算分析.

| Abstract: | The deterioration of bearing capacity of corroded reinforced concrete members with large-eccentric flexure and compression was studied.Proposed are two bearing capacity calculation models,namely,the one for the before cracked-corroded reinforced concrete members with large eccentric flexure and compression in consideration of biaxial stress caused by corroded expansion forces around steel bar and the one for the after cracked-corroded members in consideration of section size loss.The experimental result shows that experiment data are consistent with calculated value.The model can be used in calculation of bearing capacity for corroded reinforced concrete members with large eccentric flexure and compression. |
