134 • Total steel weight: 12 lock gates weighing ± 62 tons, amounting to 744 tons in total • Dimensions: Height: +/- 8, 40 m • Overall length: +/- 14, 10 m (total width when closed +/- 25 m) • Thickness: +/- 1, 50 m Description of the project The lock complex of Evergem (situated near Ghent) lies on one of the most heavily trafficked routes in Belgium. To maintain a safe and reliable passage of cargo- and leisure-ships on this important junction, the government decided to update the complex. As a part of this update, 12 lock gates had to be replaced. Use of Scia Engineer Description of technical questions to be solved with Scia Engineer The lock gate has a quite complex geometry: the presence of tubes cutting through an inclined plate, the global section is slanted instead of a rectangular box; the presence of an airbox… This complexity necessitated the use of a detailed FEM-model to simulate the real behaviour with all its intricacities. An independent, simplified beam-model was used to double-check the veracity of both models. The low ratio between height, width and rise disrupted the normal working, in a three-hinged arch.
