Structural health monitoring of a cable-stayed bridge using wireless smart sensor technology: data analyses
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...

متن کاملCondition assessment of long span cable-stayed bridges based on Structural Health Monitoring Techniques
This paper presents long-term condition assessment approaches of cables and bridge decks under in-service loads based on Structural Health Monitoring (SHM) technique. Aiming to the critical structural components, three important issues related to the long term performance evaluation, including loads and responses modelling, resistance degradation and fatigue life assessment, were investigated i...
متن کاملStructural Design of Cable-stayed Bridges
Cable-stayed bridges are extremely elegant and very effective structures and they are also architectural landmarks. The combination of multiple simple systems allows for a structure where the role of each of its components is well defined. When a cable-stayed bridge is chosen, the initial design phase is of utmost importance. The characteristics of the structure and whether if it is mainly cons...
متن کاملStructural Behaviour of Cable - stayed Bridges
Cable-stayed bridges have emerged as the dominant structural system for long span bridge crossings during the past thirty years. That success is due to a combination of technical advancements and pleasing aesthetics attributes. The interaction of the various structural components results in an efficient structure which is continuously evolving and providing new methods to increase span lengths....
