这座步行桥位于伊丽莎班女王大街,它并连接克洛克与奥斯坦德。它有两个功能:一方面,坐落于堤围泽地上的桥把海堤与绿化带连结起来,脚踏车爱好者和行人得以观光。另一方面,桥标志出海滨城市克洛克-海斯特的入口。桥的静态模型是一道102米长,横卧于四个支撑点上的连续横梁,使跨度处于28m/46m/28m的比较理想状态。

结构形式由开始的手绘草图转变为数字处理:由软件计算所需材料最小用量和开口的形状。由此得出最佳形状。桥从概念意图出发,由12mm厚的钢板焊接形成一个钢“吊床”的构件,然后将混凝土面层铺设在其上。为了抵抗水平方向翘曲引起的剪力效应,混凝土面层的边缘沿着中心轴方向倾斜了45度。

Situated on the Queen Elisabeth Avenue, connecting Knokke with Ostende, this pedestrian bridge full fills two functions. On the one hand, the bridge connects the sea dike with a green zone in the “Polders”, creating tourism possibilities for cyclists and pedestrians. On the other hand the bridge symbolizes the entrance into the marine city of Knokke Heist. The static model is a continuous beam with 102m length that rests on 4 supports. This creates an ideal span division of 28m/46m/28m.

The structural form was first hand sketched, then digitally processed: a software program computed the minimum amount of material required and thus the shapes of the openings. The result is an optimized shape. From a conceptual point of view, the bridge consists of welded bent steel plates of 12mm thickness, forming a structural steel “hammock” to which a concrete deck is tied. To resist shear forces, caused by the bent shape in plan, the sides of the plates are inclined at 45°, with respect to the central axis.
