| Abstract: |
The new JTI Headquarters constitute a novel architectural landmark in Geneva. The nine-storey building stands on a triangular shaped parcel; it is characterized by three main tubes creating an open environment on the ground floor which boasts a public pedestrian passage. The facade trusses create an impressive 60-meter-span cantilever on the north-east side. On the south-west side, the building also lifts off the ground in a bridge-like fashion spanning over 80 meters. The main frame is composed of three-dimensional steel trusses supporting light-weight composite slabs without intermediate supports. Specific procedures, namely, controlled unpropping, jacking and temporary tie-down of the structure, allowed for safe cladding installation and control of building deformations. Advanced natural fire analysis led to a consistent reduction of fireproofing measures of the steel floor framing. |
