POSSIBILITY OF FATIGUE-FREE STEEL GIRDER BRIDGES WITH SIMPLE TRANSVERSE-STIFFENING SYSTEMS BASED ON LARGE 3D FEM ANALYSIS

This paper aims at developing fatigue-free girder bridges with simpler transverse stiffening systems. The 3D structural behaviour of a three-I girder bridge is analysed by the Finite Element Method (FEM) with large numbers of degrees of freedom. Using a bridge with conventional transverse stiffening members such as lateral bracing, cross beam and sway bracings, the effects of removal of the above members on global/local behaviour of the bridge is studied from the viewpoint of fatigue-proneness. The systems, leading to easy fabrication and maintenance, are discussed. (A) For the covering abstract see IRRD 882313.
