[2E06-10-01] Evaluation of effect non-structural members on main structural bending stiffness of steel composite railway bridge
Keywords:non structural member, bending stiffness, composite girder, steel deck girder, steel through girder, track, rail
This study evaluated the effect of non-structural members on the main structure by 3D finite element analysis for steel composite bridges. Although the effect of secondary members on the main structure stiffness of open-floor steel bridges is small, the effect of rails is large, which greatly depending on the restrained state of the track fastening devices. In composite bridges, vibration-reduction concrete and roadbed concrete have a large effect among non-structural members on the main structure stiffness and slab cracks due to negative bending moments section of continuous girders can be ignored since the decrease in stiffness increase rate to is small.
