Flint River Form Traveler Project Report (PDF) –

For this project, we redesigned an existing form traveler already owned by the contractor to fit the new bridge cross-section. We performed the required structural analysis and produced the modification drawings. We also calculated the form traveler reactions on the bridge and the expected formwork deflections. These parameters are required for checking construction stresses and for developing proper casting curves for the bridge superstructure. The immediate form deflections are combined with long-term creep and shrinkage deformations to determine the theoretical formwork elevations at the time of each segment pour. After all long-term losses have occurred in the concrete and post-tensioning steel, the bridge will have assumed its theoretical design profile.
