Prestressed concrete bridge over Black River, SC

We did a project with a 60 feet prestressed concrete bridge. This model is a half of the bridge due to the symmetries of load and geometry. The actual bridge is comprised of six spans of 60 feet. The bridge is located over Black River of SC377. This model simulated the construction sequence of the bridge: (1) release the prestresses in strands of the bridge girder; (2) cast the deck of the bridge; (3) apply the wheel loads and lane load. The deflection and stresses were predicted for each stage.
