| 摘 要： | 对采用不同材料修复的轴心受压钢筋砼柱进行了实验研究，并进行了ＡＮＳＹＳ有限元模拟分析，研究了修复材料与柱本体砼的弹性模量比ｎ．强度比α，修复时柱的卸载程度、修复区域相对深度等因素对修复后用筋砼柱力学性能的影响．认为修复材料与柱本体砼的弹性模量比ｎ是导致钢筋砼柱力学性能不相容的最主要因素，它与强度比α共同决定修复柱的极限承载力．

| Abstract: | Experiments and ANSYS finite element simulation analysis were conducted for making a research on the mechanical behaviors of the patch repaired reinforced concrete column with different repair materials. The influence of the elastic modulus ratio. strength ratio between repair materials and substrate concretes and load relief percent were analysed. The elastic modulus ratio is the most important influential factor in the mechanical properties incompatibility of the patch-repaired column The ultimate capacity of the patch-repaired column are determined by the elastic modulus ratio and strength ratio between repair materials and substrate concretes together. |
