University of Technology Sydney Central Staircase

State-of-the-art structure for the new UTS Central

Bonacci Group was engaged on the University of Technology Sydney Central Staircase project to provide specialist design for the three feature staircases connecting levels 4 to 7. 

This challenging project involved detailed finite element analysis of the spiral steel structure. The long helical spans are achieved by using circular hollow sections as primary torsional members, with additional stiffness provided by the structural steel stair treads and balustrades.

The stairs are inspired by the repeating twin helical structure of DNA where the steel fabrication and installation were performed by Active Metal.
