Structural Response of Concrete Skew Box-Girder Bridges – A State-of-the-Art Review

Abstract

Box shaped support girders are considered as the most efficient support section for bridges and flyovers, as they provide enhanced structural efficiency, superior stability and serviceability of the bridge, as well as pleasing aesthetic appearance and better economy. In case of multi-lane bridges, multi-spine and multi-cell box sections are commonly used. Sometimes, due to space constrain, skew bridges are built especially in congested metropolitan areas. Due to presence of skewness, the structural behavior of box-girder bridges is significantly affected. Several experimental and numerical studies have been made to examine the effect of skewness on the structural response of box-girder bridges subjected to static and/or dynamic loads. The aim of the current paper is to review the literature published on the structural behavior of skew box-girder bridges subjected to static & dynamic loads including seismic effects. Moreover, this study also reviews the effect of skewness on load distribution among the multi-spine/cell box-girders bridges and presence of diaphragms in the bridge.
