Railway dislevelments influence on the dynamic response of bridges

Carmen Bucur, Victor Mircea Bucur

Abstract


The main purpose of this paper is to estimate the influence of railway dislevelments on the dynamic response of railway bridge structures subject to the load of a passing vehicle. The study covers six types of bridge structures: four steel structures and two prestressed concrete ones. A parameter study is performed to determine the dynamic amplification factor values and their variability as a function of railway dislevelments characteristics: amplitude and length. A special computer programme developed by the authors is used in the respective parameter study.
