通过数值模拟建立有限元模型并模拟损伤,采用柔度差法对某斜拉桥算例进行损伤识别,经过数值试验的验证,损伤效果较好,证实该柔度差法可以实现对大型斜拉桥结构的损伤识别。
通過數值模擬建立有限元模型併模擬損傷,採用柔度差法對某斜拉橋算例進行損傷識彆,經過數值試驗的驗證,損傷效果較好,證實該柔度差法可以實現對大型斜拉橋結構的損傷識彆。

The finite element model is established and the damage is simulated through numerical simulation.The damage of cable-stayed bridge is identified with flexibility difference method.Through the numerical test,the essay finds out good damage effect,and identifies that flexibility difference method can realize the damage identification for large-scale cable-stayed bridge structure.
