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 structure of the bridge 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.
