Pulkovo Airport terminal hall steel structure

The first stage of Pulkovo International Airport new terminal hall was put into operation in 4th December 2013. The second stage after complete transfer of the operations from the old Pulkovo-1 and Pulkovo-2 terminals will begin in early 2015. The striking new roof of the terminal building has beendesigned to accommodate the varied extremes of the Russian climate. It has been conceived in modular bays, expressive structural 'trees' being positioned such that it can support the weight of standing snow experienced in the winter months. Steel structures constitute a roof of the terminal hall, while supporting structures are made from reinforced concrete. Report describes the architecture, structure geometry, static scheme and main characteristics. Two independent calculations were compared and bearing capacity of the roof was checked.
