New National Stadium in Bucharest Romania

Shock-proof grandstands

The Arena Națională is a world-class stadium with covered grandstands and VIP lounges for 55.000 football fans. The Arena also houses conference rooms, restaurants and a six-storey underground car park with 108.000 m2 of parking space. KREBS+KIEFER produced the structural design for this solid structure, made from in-situ concrete and prefabricated elements.

Extensive earthquake calculations were a key factor in determining the bracing system. These were deemed necessary as Bucharest sits in one of Europe's most seismically active regions. The support structure of the elliptical stadium roof is reminiscent of a spoked wheel. The filigree, translucent roof comprises an external pressure ring, an inner tension ring and 40 pairs of cables.
