Abstract
Bridge Redundancy Evaluation is getting more attention in both designing new highway bridges and repairing or retrofitting old bridges after several bridge collapses or failure incidents happened around the world in recent years. This study is tempted to evaluate effects of secondary members on redundancy of three-span composite twin I-girder bridge. Two types of secondary members were studied including I-shape transverse beams and L-shape X-type bottom lateral bracing. Results show that three-span composite twin I-girder bridge can be considered as redundant. The redundancy level can be increased by adding bottom X-type lateral bracing. I-shape transverse beams alone is found not effective in increasing the redundancy of the bridge, but is found useful to increase the efficiency of the bottom X-type bracing to increase the load carrying capacity and redundancy of bridge.
