The San Shan Bridge spans across the Gui River and will be an integral part of theinfrastructure program for the Olympic Winter Games 2022 in Beijing and connects thecity center with Zhangjiakou. Architecture studio Penda has teamed up with engineering firm Arup to design a bridge made up of overlapping rings for the 2022 Winter Olympics in Beijing.
The structure of San Shan Bridge connects the shores of Gui River through a 452 meter long bridge deck and is divided in three sets of cross-connected arch-like steel structures with a maximum span of 95 Meters. The sequence of arches form a prestressed doublehelix, which intersects and supports each other on their bottom and top. The helix is designed and engineered to be as slender as possible and positioned to offer the best structural performance. The bridge deck is suspended from the structure by high-strength steel-cables, that connect to the arches in a cross-weaving way.
