Dynamic analysis of a cable-stayed deck steel arch bridge

Construction of Nagisa Bridge Hybrid System of Cable-stayed Pc Bridge and Steel Suspension Bridge

Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...

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...

Investigation on Deck-Stay Interaction of Symmetric Harp Cable-Stayed Bridge

This paper provides a variety of viewpoints to illustrate the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges, which is validated by a symmetrical structure. Based on the smooth and convergent bridge shapes obtained by the initial shape analysis, the one-element cable system (OECS) and multi-element cable system (MECS) models of the symmetric h...

Advanced Cable Stayed Bridge Construction Process Analysis with ANSYS

Seismic Analysis (Non-linear Static Analysis (Pushover) and Nonlinear Dynamic) on Cable - Stayed Bridge

Pushover analysis application development is greatly increased in recent years and numerous advanced methods to evaluate the seismic pushover are provided. Because these methods have been proposed mainly for building structures and given the fundamental differences between the behavior of bridge structures and buildings using pushover methods on the bridge structure with the uncertainties faced...
