Abstract

This contribution describes the architectural and structural solutions of a unique pedestrian footbridge in Hradec Králové. The new significant construction was built over the Elbe River in the pedestrian area. The bridge design was challenging for architects, planners even though contractors, especially due to accounting for the influence of shipping traffic. Completed structure has two asymmetrical spans, whereas the main span across the river is 69 m long. In the final static scheme, the structure forms a virtual Vierendeel truss of variable height. A slender UHPFRC bridge deck supported by a pair of cables through thin steel crossbars creates a delightful bridge, which has become a new symbol of the city.

赫拉德茨-克拉洛韦易北河上的步行桥
这篇论文介绍了赫拉德茨-克拉洛韦一座独特人行天桥的建筑和结构解决方案。这座新的重要建筑横跨易北河步行区。这座桥的设计对建筑师、规划师甚至承包商来说都极具挑战性,尤其是要考虑到航运交通的影响。建成后的结构有两个不对称的跨度,而跨河的主跨度为 69 米长。在最终的静态方案中,该结构形成了一个高度可变的虚拟 Vierendeel 桁架。细长的 UHPFRC 桥面由一对通过细钢横梁的缆索支撑,形成了一座令人愉悦的桥梁,成为城市的新标志。
