A 3D-printed concrete bridge referred to as Diamanti has been unveiled on the Time, House, Existence exhibition in Venice as a part of a analysis collaboration led by the College of Pennsylvania. The two.5-meter-long construction was designed by Professor Dr. Masoud Akbarzadeh and his crew on the Polyhedral Constructions Laboratory, with fabrication dealt with by Dutch firm Vertico.
The bridge consists of 9 prefabricated concrete segments, every 3D printed utilizing a robotic arm and a two-component cementitious combine developed by Swiss firm Sika. The segments characteristic inside voids and floor patterns designed to scale back materials utilization whereas sustaining structural efficiency. Eight metal cables maintain the segments collectively via a post-tensioned system that requires no adhesives or grout, permitting all the construction to be disassembled and recycled.
The design makes use of Polyhedral Graphic Statics (PGS) methodology to optimize power distribution via the construction’s geometry. Every section incorporates anticlastic diamond surfaces that present stiffness and cargo distribution whereas minimizing concrete utilization. The Venice show mannequin measures 2.5 meters in size with a depth of 26 centimeters, although the design has been examined efficiently at a full 9-meter span.
The mission concerned a number of trade and educational companions throughout totally different phases of improvement. Sika Group created the specialised concrete combine for robotic printing, whereas Carsey 3D managed fabrication logistics and AEVIA offered post-tensioning experience. Structural evaluation was carried out by researchers at Metropolis School of New York and Villanova College, with bodily load testing carried out on the CERIB institute in France.
