Steel Fire Escape Stair

Designed for the emergency egress needs of the building, this steel fire escape was engineered as a free-standing system that is stable on its own, without being structurally anchored to the existing building. Stair flights, landings and primary members were assessed together under vertical and lateral loads, with the requirement that the system provide the necessary stiffness and stability within its own structural arrangement. Alongside safe use, the design prioritised economical section selection, ease of fabrication and buildability on site.
