| 摘 要： | 混凝土柱抗震加固方案中遇到的应力、应变滞后这无法改变的突出特征,是影响加固效果的关键因素;套层加固法的混凝土自身体积变化也是不可忽视的因素,还可能改变原柱的受力特点及原结构的动力特性,而钢构架加固法副作用较少。通过加固方案可行性分析及探讨,阐述了各种加固方案的优缺点,供参考。 |
| 关 键 词： | 应力应变滞后 体积变化 受力特点 动力特性 加固方法 |

| Abstract: | The lag of stress and strain in strengthening concrete column is an outstanding and unavoidable character which dramatically affects the strengthening effect of concrete columns.Using covering strengthening method,the change volume of concrete should not be ignored,and the original force characters of columns and dynamic features of the structure may be changed.Strengthening method using steel frame may result in few side-effects.The feasibility research and discussion about various strengthening methods of concrete are carried out,and the advantages and disadvantages of strengthening methods are expounded.It can be the reference for engineering. |
| Keywords: | the lag of stress and stain the volume change force character dynamic features strengthen method |
