  • Forms of ConstructionDesign AspectsConstruction and Maintenance AspectsWhy Choose Steel Box Girders?ResourcesSee AlsoExternal LinksA box girder bridge is one in which the principal structural element is one or more closed cells, acting in bending. Box girders are used for highway bridges, railway bridges and footbridges different structural forms are chosen for each of these applications.Shear buckling of corrugated plates with edges elastically This paper presents an estimation of the elastic shear buckling capacity of corrugated plates with edges elastically restrained against rotation. The corrugated plate possesses higher shear buckling capacity compared to an unfolded flat plate. It has been used to replace the concrete web in PC box girders in recent bridge constructions in Japan. Bridge Bearings - CaliforniaBridge Design Specifications (Article 14.2.6) state that the shear deformation shall be taken as the maximum possible deformation caused by creep, shrinkage, post tensioning, and thermal effects unless a positive slip apparatus is installed.
