Brasilia National Stadium Mané Garrincha


Inspired by Oscar Niemeyer's work, the Brasilia National Stadium Mané Garrincha was rebuilt and extended for the 2014 Soccer World Cup according to the plans of Castro Mello architects and gmp. With a capacity of more than 72.000 spectators, it is the second largest sports venue in the country and strives for LEED Platinum.

Situated in the Ayrton Senna Sports Complex, the new Brasilia National Stadium replaces the old Mané Garrincha Stadium opened in 1974 and demolished in 2010. The new stadium, inaugurated in May 2013, was designed to receive not only football games, but also concerts, shows, conferences and meetings. It offers 74 cabins, 40 bars, two restaurants, 14 diners and 276 toilets.

According to the FIFA requirements, the stadium is situated close to public transportation and features seating for more than 72.000 spectators, press and VIP areas and all necessary installations of a modern football stadium, including excellent accessibility to all areas.

The stadium's façade consists of 288 concrete columns, arranged in three concentrical circles. The space between the columns, the so called esplanade, covers 617.870 m2 and allows access to all levels of the stands independently and quickly, through 19 gates and 158 turnstiles.

The internal circulation is realized by means of 50 ramps, four escalators, 60 normal stairs and 20 elevators. The evacuation time of the place is up to eight minutes.

Design
The new multifunctional stadium was created following the architectural traditions of Brasilia, the country's only 50 year-old capital city. The interplay between ramps, bridges, long and slender columns and the monumental circular roof are the stadium's key design characteristics.

The reinforced concrete structure of the stadium's roof comprises the "esplanade", the three circles of columns as well as the concrete compression ring of the cable-net roof. The entire structure is a perfect circle based on 96 radial and 3 tangential ring axes of the concrete pillars. The 288 concrete pillars are up to 61 m tall and extremely slender, with diameters of only 1,2 to 1,5 m.

The 22 m wide tapered concrete compression ring has an outer diameter of 309 m. The great tensile forces of the cable structure are anchored in the radial walls by means of strand-bundle cables. The suspended roof consists of a cable-net that features 48 radial cables. These connect the compression ring to the tension ring. On top of this there are slender radial and tangential steel truss girders that are continuously stabilized by the pin-jointed  membrane arches. The entire roof is wrapped into a PTFE fibreglass membrane.

Sustainability

One of the major aims in the design of the new stadium was the improvement of its energy efficiency. The Brasilia National Stadium strives for the highest Green Building certification possible, LEED Platinum, and is intended to be the most energy-efficient sports venue in the world.

The hot and dry climate of Brasilia was a major factor to be taken into account in the sustainable design. Taking advantage of the winds in the area, the stadium's open façade, with the concrete columns, allows for maximum natural ventilation which reduces the heat inside the stadium.

The roof protects the spectators from the strong sun and is self-cleaning, using the photo-catalytic process for the removal of dust. Lighting is entirely realized with LED lamps in order to achieve the planned 20% energy reduction. In order to avoid shading and ensure a homogeneous light field, the stadium is equipped with 465 reflectors, with two thousand watts of power each, that illuminate the lawn.

Water shortage is also an important issue in this region, therefore the aim is to reduce up to 50% the venue's  drinking water consumption. This is achieved by using technologies that guarantee an efficient water use (toilets, faucets,..), strategies for the reuse of water and practically irrigation free vegetation. Rainwater is collected on the roof and stored for its use in and around the stadium.

New green spaces were created all around the arena, local plants used to the dry climate convert the area into a biosphere. Increased vegetation helps to reduce the heat island effect in Brasilia's city center.

The materials of the demolished old stadium were reused in the new construction, for landfill, or recycled.

ArcelorMittal steel
For this project, ArcelorMittal Brazil supplied mainly rebar for the reinforced concrete structure, but also meshes, profiles, wires and flat products. In total, the supply covers 26.000 tn of long products and 55 tn of the fencing solution Securifor 3D, produced by the Belgo Bekaert Arames joint venture site.
