THE ROLE OF CONSTRUCTION METHODS ON THE CONCEPTUAL DESIGN OF A SEGMENTAL PRESTRESSED RC BRIDGE
This paper addresses the design of a prestressed reinforced concrete bridge to be built in Palermo. The bridge features a 104-m central span and 2, 18-m side spans, and rests on slanting piers it is solidly attached to. It also features a single-cell boxed cross-section. Precast segments are placed towards the mid span, connected by posttensioned tendons. These segments are supported by 2 temporary piers and tie rods set in the ground under the abutments during intermediate construction stages. The bridge is connected to the mid span section at the final stage. This construction method leads to different timing creep at each element. Assessment of concrete creep-induced stress redistribution is then essential. Analysis shows wide stress variation in the 2 limit conditions based on elastic effect overlap on variable and final static arrangements.
