Creep and Shrinkage Effects in Segmental Bridges
Segmental bridges started in the United States in the early 1970s with the precast Corpus Christi Bridge in Texas and the Pine Valley Bridge in California. Since then, the effect of creep and shrinkage effects on segmental precast and cast-in-place bridges has been under constant debate. Many design engineers, however, are still unsure what effect creep and shrinkage has on the final stresses of the structure. Shrinkage is the property of concrete to change in volume independently of the loads it sustained. Both creep and shrinkage are time-dependent deformations and may occur concurrently. In this paper, the writers present a parametric study by comparing results of structural analyses with and without consideration of creep and shrinkage effects. All structural analyses have been carried out using TANGO, a commercially available software specially designed to handle this type of structures.
