In situ testing and nonlinear modelling for a cable-stayed timber footbridge

Investigation of Pedestrian Walking Loads on a Cable Stayed Footbridge Using Modal Testing and Fe Model Updating

This paper describes the finite element modelling, dynamic testing and finite element model updating of a newly constructed, 35m span, cable-stayed footbridge. A numerical simulation, using an updated FE model, was conducted to evaluate the accelerations that would be induced by a walking pedestrian. The results from the simulation were compared to corresponding experimental measurements, and w...

Identification, Model Updating, and Validation of a Steel Twin Deck Curved Cable-Stayed Footbridge

To perform a realistic reliability analysis of a complex cable-stayed steel footbridge subject to natural hazard and corrosion, this article addresses a rational process of modeling and simulation based on identification, model updating, and validation. In particular, the object of this study is the Ponte del Mare footbridge located in Pescara, Italy; this bridge was selected as being a complex...

Geometric 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...
