The training is designed to guide you through the modeling process for an parametrical 3D Prestressed concrete bridge model using Allplan Bridge and using Allplan Engineering for further detailing of the bridge. The used example is a hollow box concrete girder bridge with three spans. The length of the bridge is 80 meters, and the span lengths are 25, 30 and 25 meters. The bridge has two piers with variable dimensions along the height of 10 meters. The bridge axis is curved in plan and in elevation.
