A STUDY ON RATIONALIZATION OF THE SHAPE STEEL BRIDGE

Abstract

A new type shape-steel bridge is proposed, to rationalize fabrication and erection by integrating main girders and composite slabs with steel panels, by elimination of slab-haunch and simplification of connection between slab and girder, by reducing transverse stiffening structures, and by changing simple girder into continuous girder on site. This paper describes the validity of developed design methods through analytical and experimental studies. It is expected that this study contributes to expand the application of steel bridges.
