Abstract

The dynamic vehicle-track-bridge-soil interaction is studied on high speed lines. The analysis is carried out using a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to the train passage [...]

Abstract

This paper studies the effect of vehicle-bridge interaction (VBI) on the vibration of the supporting bridge, and subsequently proposes a decoupled analysis scheme for the VBI problem with reference to high-speed railway systems. The study examines the VBI problem analytically and [...]

Abstract

The objectives of this work are focused on giving an answer to the problems presented in the operation of a railway bridge, using the FEM-DEM numerical technique considering static and dynamic loads. The purpose is to find out the existing breakage mechanisms in the bridge.

Abstract

This paper refers to the design and calculation of a 30,00 m section of metal beam, for a proposed railway bridge in the city of El Vigía, capital of the Alberto Adriani Municipality of Mérida State, Venezuela. The location of the bridge corresponds approximately [...]

Abstract

The present work presents  numerical methods to evaluate the global dynamic response of railway bridges.the structural response of an existing reinforced concrete railway bridge is obtained via the Modal Superposition Method, using a finite element three-dimensional numerical [...]

Abstract

Railway network is subject to increasing travelling loads and traffic frequency. In addition, since most of the bridges were built in the last century, they are subject to ageing and degradation. It is therefore necessary to develop proper structural health monitoring systems that [...]
