Structural problems on the roof of Joao Havelange Stadium in Rio de Janeiro have prompted officials to close the arena until the issues have been addressed. The metallic roof weighs more than 3,600 tons and is "supported by four complex supporting white steel arches -- designed in a rhythmic repetition of irregular forms -- and cable-stayed strings" that make the roof appear "to hang in mid-air." And it appears that the elements that make that happen are causing the problems, which could pose a risk for spectators, according to Rio de Janeiro Mayor Eduardo Paes.
