Hatay Stadium with a capacity of 25,000 was designed in accordance with the programs specified in UEFA and FIFA standards. Lower tribunes are for 15,000 people and upper tribunes for 10,000 people. Between these two tribune floors, there are lodges. In the western tribune, rooms of different sizes and functions have been planned for the referee rooms, the observer rooms, the locker rooms for players, the warm-up areas and the various rooms for the press. Entrances for VIP and management, event areas and rooms with various functions are also located in the western tribune.
For sportspeople, referees, VIP, spectators, protocol and media members, entrances were provided on the ground level (±0.00) of the western tribune. In the north, south and eastern tribune, the entrance and reception areas were designed at the ground level in order to meet the spectator density easily.
While the entrances and circulation areas of the spectators, media, lodge, VIPs, sportspeople and security guards were separated from each other in the stadium, a sufficient number of open parking lots were built around the stadium for the audience, VIP, press, protocol and team vehicles. While reinforced concrete carrier system was used in the tribunes of the building, steel systems were used on the roof and facade. While creating the steel structure system, a modular system that provides ease of manufacturing and assembly was preferred.
In the project, facilities such as direct sunlight control, save of daylight, natural ventilation, solar and wind energies were used in accordance with the climatic comfort for Hatay. In order to eliminate the causes of global warming and climate change today, energy-efficiency design criteria were applied in this project.
It was aimed to keep the tribunes under the roof at optimum temperature by preventing the burning sunlight of the summer season with the materials used in the building shell. At the same time, ventilation of the heated air is provided by using passive wind energy, with the tears formed on the side facades. The convex curvature created on the side facades of the structure creates shadow areas around the building. On the roof of the stadium, sufficient eaves trough and downspout were created to collect rain water, and the reuse of this water was provided by a third installation system.
ENGINEERING DESCRIPTION
While the main load bearing system of the structure consists of 16 reinforced concrete blocks arranged as a frame, the facade and roof system are anchored to these reinforced concrete blocks with a holistic steel shell system. 76 steel trusses forming the shell system are 56 meters long and have a 46-meter cantilever beam share. The shell of structure was designed as a double skin system. The flooring of the audience foyers between the double walls is a composite system.
Wind and snow loads affecting the steel load-bearing system were taken into account in the calculations. In addition, Turkish Earthquake Regulation and steel structure regulations were used. In total, 3500 tons of steel were used. Due to the fact that steel allows modular and flexible design, the plastic structure with softer lines, assembling has become faster and easier. Considering the size of the stadium structures, the advantages of the wide spans, long cantilevers and the visible details of the load bearing steel system have been converted into a symbolic form.
