Análise dinâmica e estudo de conforto humano das arquibancadas do Estádio Nacional de Brasília.

Abstract

Over the years, many soccer stadiums in Brazil have been designed to withstand accidental loads (people loads) to be of static type (4kN/m2). However, based on the changes in the people s behaviour, especially in soccer matches, through the action of groups of fans and also with the use of these structures for music shows, these structural systems have been subjected to dynamic impacts related to the dynamic nature of the applied loads. Therefore, some of these stadiums have presented excessive vibration problems and have required an effective consideration of the dynamic loadings in the structural design. This way, this research aims to study the dynamic behaviour and evaluate the structural system performance of the Brasilia National Stadium grandstands, when the human comfort is considered. It should be noted that the stadium was designed and constructed to be used at the World Cup 2014, held in Brazil. The results achieved during the development of this study are compared with those provided by design standards and international recommendations. The presented results show the relevance of the dynamic analysis in the structural design of soccer stadiums, with respect to obtaining relevant data for human comfort and as well safety of users of this type of structure.
