| 摘 要： | 为了对钢桁架结构的损伤情况进行比较准确的检测,应用了柔度曲率幅值突变系数法.首先应用ANSYS对钢桁架结构的单个或多个损伤同时出现的情况进行了数值模拟,然后用一个钢桁架模型对ANSYS的计算结构进行实验验证.数值模拟的结果表明:用柔度曲率幅值突变系数法可以对钢桁架结构单个或多个结构同时出现的情况进行比较准确的判定.实验结果与数值模拟结果基本吻合. |

| Abstract: | For precisely testing the damage of the steel truss,the method of the sudden change coefficient of the flexibility curvature was used.At first,ANSYS simulate the condition of the single or multi damage in a steel truss and use this method to test these damage were used,then a test to validate the results from ANSYS was done.The results of the simulation indicate that using the method of the sudden change coefficient of flexibility curvature,the single or multi damage of the steel truss were tested more precisely.The results of the test are primarily inosculate to the results of the simulation. |
| Keywords: | steel truss girder damage test the sudden change coefficient of flexibility of curvature |
