Gaziantep Stadium

The stadium in Gaziantep, home of Zeugma which is the largest mosaic museum of the world, is 10 km away from the city center.

The stadium in Gaziantep, home of Zeugma which is the largest mosaic museum of the world, is 10 km away from the city center.
Constructed in Beylerbeyi in Sehit Kamil district and handed over to the Ministry of Youth and Sport is located on a plot of 106.000 sqm.
Gaziantep Stadium, with its strategic location, is a connection point between industrial and residential areas and various alternatives are available for transportation.
Structure being built in a junction point of industrial and residential areas is an important focus point in the fussion of two social fabrics. With its dimension,architectural design and location, the stadium is deemed to be a landmark of the city.
Sunblinds are used in south facade of the structure since Gaziantep is under the influence of Mediterranean climate while red and black, colors of Gaziantepspor, are used in structural shell. Stadium’s facade resembling to mosaics reflects the history and culture of the city.
The tribune layout of the stadium designed with a capacity of 33.000 and in accordance with UEFA criteria was named as eastwest and north-south. Sufficient number of toilets and buffets were designed under each tribune for the spectators. Car park
areas planned for comfortable transport is a significant part of the design. Areas under the tribunes of the stadium are used for 12 sports halls for individual sports branches.
Structural Details
New Gaziantep Stadium constructed
within the boundaries of Gaziantep Sehitkamil municipality was designed with a capacity of 33.000 spectators and in line with FIFA and UEFA standards for international organizations. Load bearing system of the structure is reinforced concrete having 15 expansion joints and composed of 16 blocks. Facade and roof supporting systems are composed of reinforced concrete and structural steel,
where steel members are anchored to reinforced concrete structural elements. A composite slab was formed by having the steel shell connecting to the reinforced concrete structure as a sub-layer for the slab. In addition, secondary steel for PTFE membrane in the facade is connected to the facade steel structural nodes.Roof is composed of 76 trusses having a length of 46 meters, 40 meters of which is a cantilever. These trusses are fixed to transfer tension to facade steel columns at one point and compression to reinforced concrete structure at another. PVC membrane is used as covering material at the lower part of the roof. Sub-trusses are placed in roof trusses for roof membrane forms. SAP2000 software was used for the analysis of the steel structure while TS498, TS500, TS648, TS4561, TS3357, DBYBHY (Regulation for the Structures to be Built in Disaster Areas) and equivalent foreign
standards were used in design. Loads used in analysis and design of the structure are composed of the dead and live loads such as the dead weight of the structure, roof and facade membrane with accessories, composite covering, roof snow load, load imposed due to temperature difference since the steel system is to be exposed to open air, wind load, seismic loads and catwalk loads.
Reason for preferring steel in Gaziantep stadium is the significant advantage of steel system against seismic loads. Swift construction of steel under any weather condition is another factor in the decision considering the harsh winter conditions of the region. Furthermore, elliptic form of the outer structure of the stadium constitutes another advantage for steel to provide a faster and more aesthetic appearance. Considering the short response time to requirements, use of steel has become inevitable. Steel structure rests on the reinforced concrete structure, with no contact with the ground.
A total of 2.900 tonnes of structuralv steel forming 76 axis with 15 expansion joints was used in the project. Each axis of steel structure is formed of two separate modules. Each module is formed of 1 facade shell and 1 roof structure constructed in place.
