Nov 30, 2012 · Steel has higher strength, ductility, and toughness than many other structural materials such as concrete or wood, and thus makes a vital material for bridge structures. In addition to the conventional steel, there are many types of high-performance steel (HPS) developed recently for the bridge application. Steel with low yield ratio (SN, SA440)Bridges - SteelConstructionfoBox girder bridges. Box girders comprise two webs that are joined top and bottom by a common flange creating a closed cell that offers very good torsional stiffness, which may be required on highly curved bridges.In beam and slab bridges, box girders are an alternative to plate girders at the upper end of the span range, where they offer a lower steel weight, although this has to be balanced high performance steel bridge girder compactnessC.J.

bridge girders made from A709 HPS483W steel. That is, all criteria relating to flange and web compactness, unbraced length, and bracing stiffness, when considering A709 HPS483W steel, are unconservative. New lateral bracing requirements are proposed, altering both the position of the bracing as well as the required bracing stiffness. In addition, new flange and web compactness criteria are developed for use with A709 HPS483W steel.Christopher Earls - Google ScholarHigh performance steel bridge girder compactness.
