At the end of 2017, ASFINAG erected two new bridges in the immediate vicinity of the north part of Vienna, which generated tension in different ways. The “Satzengrabenbrücke” is designed as an integral structure and contains new, maintenance-free roadway crossings, consisting of precast concrete elements placed next to one another that distributes the temperature-related displacements evenly over the asphalt above. This way, the stresses in the asphalt are limited to a tolerable level so that it remains free of cracks. Furthermore, the overpass bridge “A5.Ü20”, as an inclined post construction, triggers tension in the psychological sense of perception. A dynamic play of shapes with inclines and curvatures, which visually underpin the force transfer of the bridge, increases the overall expression and, thus, sets an accent in the middle of the new A5 north / Weinviertel motorway.
The online lecture (primarily in German) on the two new bridges on the A5 motorway will take place on 17 December 2020 from 14:00-15:00, organised by the International Association for Bridge and Structural Engineering (IABSE) Austria through Dr. Alois Vorwagner (AIT structural dynamics expert, Deputy Chair IABSE Austria), Prof. Alfred Strauss (BOKU, Chair IABSE Austria) and Dr. Roman Geier (Schimetta Consult, Deputy Chair IABSE Austria).
