After the fragility curve is established, probability of structural damage reaching each level under action ground motion can be determined according to parameters, so as calculate direct and indirect loss caused by complete earthquake prediction. This paper combines improved IMK resilience model study seismic vulnerability high-pier long-span bridges. Moreover, this obtains parameter calculati...

The vortex-induced force of bridges is not synchronized along the span direction. spatial correlation becomes obvious when bridge structure gradually increases, and mass decreases. Therefore, it important to study spanwise forces long-span ensure accuracy prediction vibration response bridges. established improved theory experimental research methods for analysis large-span by discussing during...

Cable-stayed bridges are one of the most popular types of long-span bridges. The structural behaviour of cable-stayed bridges is sensitive to the load distribution between the girder, pylons, and cables. The determination of pretensioning cable stresses is critical in the cable-stayed bridge design procedure. By finding the optimum stresses in cables, the load and moment distribution of the bri...

The development of structural health monitoring (SHM) technology has evolved for over fifteen years in Hong Kong since the implementation of the “Wind And Structural Health Monitoring System (WASHMS)” on the suspension Tsing Ma Bridge in 1997. Five cable-supported bridges in Hong Kong, namely the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge, the Ting Kau (cable-stayed) B...

Structural Health Monitoring (SHM) is a technique that involves gathering information to ensure structure safe and behaving as expected. Within SHM, vibration-based monitoring generally seen one of the more cost-effective types monitoring. However, has mostly been undertaken on long-span bridges using data collected with dense network sensors. Historically, logistical difficulty collecting shor...

The long-span multi-tower suspension bridge is widely used in the construction of river and sea crossing bridges. load-bearing safety anti-sliding its main cable are directly related to structural a bridge. Failure mechanisms discussed. Meanwhile, tribo-corrosion-fatigue cable, contact, slip behaviors saddle service assessment reviewed. Finally, research trends proposed. It great significance i...

Abstract Submerged floating tunnel (SFT) is a new type of structure across long and deep water straits waterways with good application prospects. The different from the traditional large-span bridges immersed tunnels, which can effectively avoid difficulty under construction foundation in channel, high cost large span bridge, influence typhoons heavy fog et al. severe weather on vehicle driving...
