Title: Behavior of a Typical Steel Bridge Superstructure Subjected to a Lateral Point Load on the Girder
Abstract:The object of this paper is to present the results of the static nonlinear analysis of a typical composite I-girder bridge superstructure subjected to a concentrated lateral load at the girder level. ...The object of this paper is to present the results of the static nonlinear analysis of a typical composite I-girder bridge superstructure subjected to a concentrated lateral load at the girder level. The results of the analysis have demonstrated that the response of the bridge to such loads is essentially a local phenomenon rather than a system mechanism in the sense that damage remains concentrated within a limited portion of the loaded beam. It is only when the load is applied at the diaphragm or very close to it that the load is essentially transmitted to all the girders of the bridge. Otherwise, neither the number of girders, girder spacing, nor the distance between the diaphragms have any measurable effect on improving the capacity of the system compared to the capacity of the loaded beam. In that sense, there are no redundancy contributions to such a loading scenario.Read More
