VIBRATION-BASED CABLE FORCE MEASUREMENT OF INCLINED CABLE WITH AN ATTACHED VIBRATION ABSORBER

摘要：

The vibration method based on the string vibration theory is often used to estimate cable forces from measured natural frequency, and it is widely applicable to the construction control, performance evaluation, and long-term health monitoring of cable-stayed bridge. However, the string vibration theory ignores the effects of flexural rigidity, sag of inclined cable, and attached damper, which will cause unacceptable errors in the practical applications. According to the measured vibration data of the cables of the Haiyin bridge in Guangzhou with attached damper, this paper proposed the simplified cable length reduction formula for vibration frequency based cable force measurement
