Optimization of cable vibration response signal in cable force analysis of cable-stayed bridge

Cable optimization of a long span cable stayed bridge in La Coruña (Spain)

This document describes an optimization problem of cable cross section of a cable stayed bridge considering constraints of cable stress and deck displacement. Since the bridge is still in study phase, the geometry and the mechanical characteristics are subjected to changes. In order to avoid creating different structural models, a program was produced to construct a model from geometrical and m...

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....

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...

Non-Linear Analysis of Cable Stayed Bridges

he concept of cable-stayed bridges dates back to the seventeenth century. Due to their aesthetic appearance, efficient utilization of material, and availability of new construction technologies, cable-stayed bridges have gained much popularity in the last few decades. After successful construction of the Sutong Bridge, a number of bridges of this type have been proposed and are under constructi...
