New Statistical Pattern Recognition Technology for Condition Assessment of Cable-stayed Bridge on Earthquake Load

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

An index system for the health-status evaluation of cable-stayed bridges is presented based on a set of dissimilarity measures (abbr. DM) of the cable force of grouped cables. The DMs and its corresponding health status labels derived by the serviceability limit states of a bridge are determined by the combination of the finite element method and the influence matrix method. The Monte-Carlo met...

Online Deflection Monitoring System for Dafosi Cable-Stayed Bridge

A health monitoring system was designed and installed on Dafosi Bridge, the largest cable-stayed bridge across the Yangtze River in western China. This article briefly describes an online deflection monitoring system, the most important sensing subsystem of the health monitoring system. It can be divided into two major components, one for measurement, and one for control and data processing. Th...

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...

Conceptual design of cable stayed pedestrian bridge at Taunton , Somerset

This paper intends to describe the conceptual design of a Cable Stayed Bridge at Taunton, Somerset, United Kingdom. The development of the detailed design and the critical issues associated with the aerodynamic effects, fatigue effect on cable stays, layout of cable stays, deck and pylon of the cable stayed bridge have been briefly discussed. The design aimed to meet the Client’s requirement of...
