All-advanced composite bridge superstructure represents a significant advance in the use of advanced composites in civil-structures. However, one of the critical obstacles to extensive use of advanced composites in construction is the lack of simplified and practical design guidelines. In this paper, an iterative performance based multi-scale analysis and design approach for all-advanced composite bridge superstructure is proposed. The bridge superstructure is formed from laminated FRP box girder and chopped FRP top surface plate. Several laminate designs are examined and the performance of the most efficient material and structural design of the proposed bridge is compared to a slab on prestressed concrete bridge. The results show that the proposed procedure leads to an efficient use of the materials with highest structural performance.
