| Abstrait: |
The bridge using rolled steel H-section seems very economical compared with the welded plate girder bridges due to lower material and fabrication cost. On the other hand, as the maximum web height is 900 mm, the applicable span length of the girder bridge with rolled H-section is up to 20m or 25m. A new composite girder bridge was proposed using rolled steel H-section. The superstructure is a continuous girder with rolled steel H-section and the RC slab, and the substructure is RC pier. The girder and the pier are rigidly connected by concrete and reinforcements. This new SRC bridge is basically the multi-span rigid frame structure: the steel/concrete composite girder resists at the span-center, and the steel girder covered by RC section resists at the rigid joints. The proposed SRC bridge increases the span length up to 50m, and its construction cost is much lower than the conventional plate girder bridge. |
