This example deals with a three-span bridge construction.
The static system is made up of beam elements with a T-beam section. Additional area elements will be added to account for the lateral supporting direction and to distribute the load.
The figure shows the beam elementation with tendon groups.
The dialog for defining the tendon group properties and entering the tendons at the desired lateral and longitudinal sections exemplifies the user friendliness of the Prestressed Concrete module.
The figures show the editing of the tendon groups in the section through one of the two main girders. Optionally, the resulting prestressing force curve or the tendon group coordinates are applied.
The concluding checks according to DIN technical report provide the resulting stresses as well as the required reinforcements both graphically and in a log. Here, the resulting stresses are always shown with the permitted limits.
The graphical representations of stresses from decompression or fatigue offer valuable help in evaluating the system.
