Study on the Influence of Cable/Sling Damage on the Natural Vibration Characteristics of Special-Shaped Cable-Stayed Arch Bridge Without Back Cable

Abstract

In order to study the influence of cable/sling damage on the natural vibration characteristicsof a special-shaped cable-stayed arch bridge without back cable. The natural vibrationcharacteristics of the bridge with different cable/sling damage and their different damage degreeare analysed. According to the characteristic of self-vibration of cable-stayed arch bridge withoutback cable, the structural health of bridges can be diagnosed and evaluated.

Influence Analysis of Natural Vibration Characteristics of Steel Box Girder With Single Cable Face and Large Cantilever

“…Generally, the basic natural vibration period of ordinary cable-stayed bridges is above 2s, while that of beam bridges is about 1s. It shows that the basic natural period of the studied structure is between the value of a continuous girder (rigid frame) and an ordinary cable-stayed bridge [16][17].…”
