The world’s largest concrete 3D printed pedestrian bridge

On January 12, 2019, the world's largest concrete 3D printed pedestrian bridge was completed in the Wisdom Bay Industrial Park, Baoshan District, Shanghai. The project was designed and developed by the team of Professor Xu Weiguo from Tsinghua University (School of Architecture) - Zoina Land Joint Research Center for Digital Architecture, and was jointly built with Shanghai Wisdom Bay Investment Management Company. The length of the pedestrian bridge is 26.3 meters and the width is 3.6 meters. The bridge’s structure is inspired by the ancient Anji Bridge in Zhaoxian, China. It adopts the structure of a single arch to bear the load, and the distance between the abutments is 14.4 meters. Before the bridge’s printing process, a 1:4 scale physical model was built to carry out the structure failure testing, which proved the bridge’s strength can meet the load requirements of holding pedestrians crowding over the whole bridge.The printing of the bridge uses the 3D printing concrete system independently developed by Professor Xu Weiguo's team. The system is integrated with innovative technologies such as digital architectural design, printing path generation, operation control system, printing tool, concrete material, etc. All of the concrete components of this bridge are printed with two robotic arm 3D printing systems in 450 hours.
