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...
متن کاملStatic and Dynamic Characteristics of a Long-Span Cable-Stayed Bridge with CFRP Cables
In this study, the scope of CFRP cables in cable-stayed bridges is studied by establishing a numerical model of a 1400-m span of the same. The mechanical properties and characteristics of CFRP stay cables and of a cable-stayed bridge with CFRP cables are here subjected to comprehensive analysis. The anomalies in the damping properties of free vibration, nonlinear parametric vibration and wind f...
متن کاملGeometric Nonlinear Analysis of Self-Anchored Cable-Stayed Suspension Bridges
Geometric nonlinearity of self-anchored cable-stayed suspension bridges is studied in this paper. The repercussion of shrinkage and creep of concrete, rise-to-span ratio, and girder camber on the system is discussed. A self-anchored cable-stayed suspension bridge with a main span of 800 m is analyzed with linear theory, second-order theory, and nonlinear theory, respectively. In the condition o...
متن کاملMode Identifiability of a Multi-Span Cable-Stayed Bridge Utilizing Stochastic Subspace Identification
This study investigates the mode identifiability of a multi-span cable-stayed bridge in terms of a benchmark study utilizing stabilization diagrams of system model identified by means of the stochastic subspace identification (SSI). The cumulative contribution ratios (CCR) estimated from singular values of system model was also considered. Observations demonstrated that wind speed might influen...
