摘要
为研究拉索损伤对斜拉桥的影响,建立拉索损伤模型。以某双塔双索面斜拉桥为背景,采用空间有限元模型对拉索损伤进行力学分析,探讨其拉索损伤对斜拉桥挠度和索力的影响",计算结果可为同类斜拉桥监测和维护提供参考。
For the research of the impact of cable damage on the cable-stayed bridge.,cable damage model is established T. he paper takes the space finite element model for cable damage mechanical analysis based on the background of the cable-stayed bridge with double pylons and double cable planes,and it discusses the mechanical characteristics of relationship of main girder deflection and cable force based on cable damage,the results can be used for health monitoring and maintenance reference of the same type of bridge.
