Complex joist girders

This project required joist girders of great complexity with a wide variety of shapes.

  • 11 cantilever trusses
  • 12 balcony trusses

The cantilever trusses included several angled (non-standard) members that had to be installed in the right places.

A curved hollow square section (HSS) had to be installed in parallel, for the balcony trusses, following a particular curve radius.


Challenges for steel deck

The design, detailing and fabrication of the steel deck have proven to be quite challenging. A wide variety of shear forces for the deck fasteners, different roof pitches and a sloped green roof system with shear brackets passing through the deck had to be considered.
