| Abstraksi | : | Constructability considerations are of importance in segmental bridge construction as the occurrence of failures of bridge superstructures under construction has highlighted. For a safe and economical construction process, the interactions between constructionloads and the permanent structural system, depending on the chosen erection method, need to be evaluated. Segmental bridges can beconstructed with methods like balanced cantilever construction, where individual spans are counterweighted about their substructure support. Time-dependent material properties like strength of the newly cast concrete, as well as shrinkage, creep, and relaxation influencethe structural system resistance. Resulting stresses in the unfinished bridge structure during construction can even exceed the final stressesduring service. This paper makes an educational contribution by illustrating these concepts with the case study of the Wilson Creek Bridgein Virginia. This five-span, cast-in-place bridge was constructed using balanced cantilever construction. Two form travelers were used toconstruct cantilever arms about the pier tables until the full span was finally connected at midspan: casting cycle duration for a singlesegment was 7 days. The contractor implemented major constructability changes in both the design and the construction of the bridge to facilitate a more economical construction process. |
