AbstractThis study investigated the optimum use of ultra high performance concrete (UHPC) for two- and three-lane simply supported bridges. Two designs were investigated: (i) typical cast in place concrete slab on precast/prestressed UHPC girders; and (ii) typical cast in place concrete slab on precast/prestressed UHPC girders. The study measured stress distributions and concentration zones in the girders under dead- and traffic-loads. The concrete quantities and the total areas of prestressing steel were calculated for the UHPC designs and compared to typical concrete designs.
