The Sinan Erdem Dome (Turkish: Sinan Erdem Spor Salonu), formerly known as the Ataköy Dome, is a multi-purpose indoor arena that is located in Ataköy, Bakırköy, Istanbul on the European side of Istanbul, Turkey.

It has a seating capacity of 22,500 for concerts. For the sport of basketball, it has a seating capacity of 16,000,[1] and for the sport of tennis, it has a seating capacity of 16,457 people,[3] making it Turkey's largest multi-purpose indoor venue, and the third largest in Europe (although it is not the third largest in Europe in capacity for basketball use). The arena is named after Sinan Erdem (1927–2003), who was the President of the Turkish Olympic Committee, from 1989, until his death in 2003.

Structure of the building[edit]

Sinan Erdem Dome has a steel roof structure, in a spherical shell form, with a dimensional span of 112 m × 154 m (367 ft × 505 ft). It also has two planar faces on each side, which forms an overall shuttle like geometry. The main load bearing supports of the arena's structure are 6 reinforced concrete twin columns, with an r/c support mass, which holds the tail section of the roof's form. The head section of the roof is fixed to the existing structure.

The steel trusses have fixed supports on top of twin columns. The top and bottom chords are made up of circular hollow sections, which form a triangular shape. There are three main trusses and secondary circular girders that rest on them, which builds up the skeleton structure, while trapezoidal steel sheet covers complete the roofing system. The steel roof and its supports are separate from the tribune structure, constituting an independent structure by itself.[4]

The Turkish club Beşiktaş İstanbul also used the arena to host its home games, during the 2015–16 season. Since the 2017/18 season, Anaolu Efes as well as Galatasaray play their games at Sinan Erdem Dome, following the closure of Abdi İpekçi Arena.
