Together with Buiting Staalbouw BV Almelo and based on the order by Reef Infra / Prorail we designed and constructed the total steel-, glass- and timber construction of the Passerelle (design by Onix Architects). Both main- and detail- calculations were performed using SCIA Engineer 16. The main steel construction of the Passerelle consists of 2 walkway-bridges. These bridges are suspended on 3 different support structures each with one or two stairs and an elevator. The walkway-bridges are welded I-profiles which are welded to the bottom floor-beams. Buckling of these slender I-beams was verified using the rotation-stiffness of the bottom floor-beams. The shape of the 3 support structures were taken from the architectural design and were constructed as X- and Y-shaped structures. Together with the stairs and the elevators, these X- and Y-support structures deliver the global stability to the whole structure. Each bridge is designed with a horizontal dilation (parallel with the span) to prevent internal stresses due thermal loads (fixed in the other directions). Both deformations, dynamics (comfort for walkways) and each installation phase were verified using SCIA Engineer 16. Passerelle Dieren - Dieren, Netherlands Ingenieursgroep Romkes BV Contact H.H.
