Izmir Airport | Izmir, Turkey
Four Funnel Structures, called "Elephant feet" by our client TAV International from Turkey, are designed with pipe elements. Pipe cross-section selection is an architectural decision as well as the choice of pipe cross-sections provide the structural rigidity which limits horizontal displacements under seismic loads. Full penetration welding is used at nodes located at half length of the elephant feet from the bottom. Site welding is kept at minimum by pre-production of the several separate parts between each node level before installation at the factory. Following completion of welding works, intumescent fire proofing application done on site. Interior glazing system designed with mechanical glass fixing only from top and bottom edges, with fixings connected to the horizontal steel ring element. After completion of the glass installation, the top of the funnel structures (Elephant Feet) is closed with a membrane roof to provide protection against rain and sun but the top connection between membrane structure and main roof of the terminal left open to provide natural air ventilation inside the structure.
