| 摘 要： | 结构在其建设-使用-退役这样一个相当长的过程中出现损伤和破坏是不可避免的,而这将严重影响到城市的发展和人们的生产生活情况。所以,了解损伤、发现损伤以及进行维修加固十分必要。从基于曲率模态的损伤识别指标法入手,提出一阶曲率模态比值,并用ANSYS对一钢筋混凝土单跨简支梁进行了数值仿真。重点研究了单处损伤情况下,结构损伤程度的识别,得出一些有意义的成果。 |
| 关 键 词： | 损伤识别 损伤指标 一阶曲率模态比值 |

| Abstract: | It is inevitable to occur the damage and destruction of the structure during quite long times of its construction-applicationretirement,which will affect the city's development and people's life.Therefore,it is very necessary to understand the damage and discover it and carry on the maintenance and reinforcement.Starting with damage identification index method on the basis of the curvature modal,the first-order curvature modal ratio is proposed,then it is made a numerical simulation analysis for a single span reinforced concrete simple bridge with ANSYS.The identification of structure damage degree under the damage on the single position is studied,and some significant achievements are also got. |
| Keywords: | damage identification damage index first-order curvature modal ratio |
