The stress state of the cable group in a cable-stayed bridge directly affects overall performance. A novel method for assessing grouped forces using deflection data is proposed this article. Firstly, simplified equation between variation and girder was built according to geometric relationship deformation. Secondly, threshold value force change rate single can be determined by theoretical limit...

As the demand and construction of cable-stayed bridges have increased, research on safety in event natural disasters such as fires explosions is actively being conducted. If a bridge damaged by an unexpected disaster or accident, it can cause serious traffic congestion huge economic losses. This study evaluates usability cable damage. Additionally, seismic performance impact damage are evaluate...

This paper presents a method for modeling and analysis of cablestayed bridges under the action of moving vehicles. Accurate and efficient finite elements are used for modeling the bridge structure. A beam element is adopted for modeling the girder and the pylons. Whereas, a two-node catenary cable element derived using exact analytical expressions for the elastic catenary, is adopted for modeli...

In a cable-stayed bridge the bridge deck is supported by a large number of inclined cables of varying lengths and inclinations, which are suspended from a bridge tower. Vertical excitation of the bridge deck, for example, due to traffic loading, is influencing the cables. This may result in quite complex dynamics of those cables, whose basic vibration modes are near resonances with the excitati...

This paper analyses the data collected from the 2 Jindo Bridge, a cable-stayed bridge in Korea that is a structural health monitoring (SHM) international test bed for advanced wireless smart sensors network (WSSN) technology. The SHM system consists of a total of 70 wireless smart sensor nodes deployed underneath of the deck, on the pylons, and on the cables to capture the vibration of the brid...
