The city of Bursa, the fourth most populous city in Turkey and formerly the capital of the Ottoman Empire during the fourteenth century, has a new football stadium – the Timsah Arena. The name, meaning Crocodile Arena, is derived from the local football team, Bursaspor, and was a strong influence in the stadium’s design. The structure’s most striking feature, its roof, resembles a crocodile curled around the ground, complete with open mouth. This spectacular roof covers all of the stadium’s 44,000 seats.
mageba supplied both bearings and seismic isolators to support the stadium’s roof and protect it during an earthquake. RESTON-SPHERICAL bearings of type KA 8.4 (with a vertical load capacity of 8400 kN), and RESTON-PENDULUM “Duplo” seismic isolators of type PD 7.3 (with a vertical capacity of 7300 kN) were supplied. The “Duplo”/PD isolators have two principal sliding surfaces, in contrast to the “Mono”/PM isolators which have only one. Test typing of the isolators was carried out at EUCENTRE, the European Centre for Training and Research in Earthquake Engineering, In Pavia, Italy.
