Abstract: Continuous multispan beams with stepped cross sections at the interior supports are common in construction of steel buildings and bridges. Design equations for lateral-torsional buckling (LTB) resistance in the American ...

Abstract: Continuous span multibeam steel bridges are common along the state and interstate highways. The top flange of the beams is typically braced against lateral movement by the deck slab, and in many bridges the cross section ...

Abstract: Floor trusses are often used as primary load-carrying members in a bridge superstructure. Load is typically transferred to the floor truss from the concrete deck through the stringers. The floor truss can be supported by ...
