The Theunis bridge can be seen from the Antwerp ring and is situated close to Sportpaleis, one of the largest concert halls in Belgium. The bridge is designed in such a way that each element follows the flow of forces that hold the bridges in place. The three bridges are curved in two planes and span a total length of 170 m, divided into three spans of 32.5 m, 105 m and 32.5 m. Due to the complexity of the bridge geometry, SCIA Engineer was used to check the statics and stability of each element as well as the dynamics of the bicycle lanes and the bridge resistance against fatigue. For the tram bridge, a special model was made to calculate the rail-bridge interaction, due to the transversal movement at expansion devices had to be limited to 2 mm. SCIA Engineer was used to perform non-linear calculations to determine the correct relative displacements of the rails. As the side spans are short in comparison to the main long span, the reaction forces in abutments directed upwards. It was decided to work with reverse abutments so that simple supporting devices (working mostly in compression) could be used.
