World's longest 3D-printed concrete bridge opens in Shanghai
A team led by professor Xu Weiguo at the Tsinghua University School of Architecture in Beijing has 3D-printed a 26.3-metre-long concrete bridge, which they claim is the world's longest.
The 3.6-metre-wide pedestrian bridge, which spans a canal in Shanghai's Baoshan District, was installed earlier this year. It was designed by Tsinghua University School of Architecture's Zoina Land Joint Research Center for Digital Architecture (JCDA), and built by Shanghai Wisdom Bay Investment Management Company.
According to JCDA, the bridge's arched form is informed by the 1,400 year old Anji Bridge in Zhaoxian, which is China's oldest standing bridge.
Although based on an ancient from, the institution believes that the bridge marks a step towards the emerging technology being utilised more regularly on real-world engineering projects.
