Health Condition Evaluation of Cable-Stayed Bridge Driven by Dissimilarity Measures of Grouped Cable Forces

Investigation of Wagon Derailment Moving on Cable-Stayed Bridge Due to Rail Irregularities

Integrating Bridge Structural Health Monitoring and Condition-Based Maintenance Management

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...

A New Multiconstraint Method for Determining the Optimal Cable Stresses in Cable-Stayed Bridges

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...

DESIGN OPTIMIZATION OF CABLE-STAYED BRIDGES USING MOMENTUM SEARCH ALGORITHM

Design optimization of cable-stayed bridges is a challenging optimization problem because a large number of variables is usually involved in the optimization process. For these structures the design variables are cross-sectional areas of the cables. In this study, an efficient metaheuristic algorithm namely, momentum search algorithm (MSA) is used to optimize the design of cable-stayed bridges....

Condition 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...
