Earlier this month, the world’s longest 3D-printed concrete pedestrian bridge was completed in Shanghai’s Wisdom Bay Industrial Park, a project designed and developed by professor Xu Weiguo, from Tsinghua University (School of Architecture)—Zoina Land Joint Research Center for Digital Architecture.

The 26.3-meter-long (86.2-foot-long), 3.6-meter-wide bridge, built in collaboration with Shanghai Wisdom Bay Investment Management Company, was inspired by the ancient Anji Bridge in Zhaoxian, China.

To create the single-arch bridge, Weiguo’s team developed a 3D-printing concrete system that implemented digital design and smart technology, according to Tsinghua University. The handrails are shaped like flowing ribbons, creating an impression of light, elegant movement across the pond.

Earlier this month, the world’s longest 3D-printed concrete pedestrian bridge was completed in Shanghai’s Wisdom Bay Industrial Park, a project designed and developed by Professor Xu Weiguo, from Tsinghua University (School of Architecture)—Zoina Land Joint Research Center for Digital Architecture.

While the bridge is composed of 44 hollowed-out 3D-printed concrete units, the handrails are made up of 68 units, all of which is made from composite materials containing polyethylene fiber concrete.

During the design process, the team developed a 1:4 scale physical model of the bridge to test the project’s viability. During construction, two robotic arms printed concrete components, a process that took 450 hours resulting in 33 percent material savings due to the elimination of templates and reinforcing bars.

A monitoring system installed in the bridge will provide data, including including vibrating wire stress sensors. The information will allow researchers to examine how the concrete materials perform, as well as the structural properties of the 3D-printed components.

“With the disappearance of China's demographic dividend, the demand for labor in construction projects will be increasingly [deficient],” the university writes in a press release.

“Intelligent construction will be an important channel to solve this problem. It will promote the transformation and upgrading of China's construction industry. As an important part of intelligent construction, 3D printing will play an important role in the […] development of engineering construction.”
