Owner Provincie Zuid Holland Architect A&E Architecten General Contractor Heijmans BV Engineering Office Movares Nederland BV Construction Period 01/2015 - 2/2016 The Parallelstructuur Gouda consists of two new regional roads, built to decrease traffic intensity on the main A12 and A20 highways near Gouda. One of these roads crosses the river Gouwe with a new bascule movable bridge. The bridge has a width of about 22 m and the main girder has a span length of 30 m. Therefore it is one of the largest bascule bridges in the Netherlands. The design is an orthotropic steel deck with steel main girders. The process of designing of a bridge with a steel bridge deck is dominated by the fatigue testing. This means a very detailed model in SCIA Engineer was required, with a fine mesh, and a model made with only plate elements. From this model, influence lines could be exported and a fatigue test carried out. The strength and stability verification is also done using this model, as well as determining the counterweight for balancing the bridge. Special attention was paid to the stability of the web plate around the main centre of rotation. A specific demand was that this plate could not have stiffeners. Consequently a combination of plate buckling and global buckling can occur. Since the plate is not rectangular, no proper Eurocode calculation was possible, so a non-linear calculation was done using SCIA Engineer.
