The European football championship in June 2004 in Portugal required the construction of several new stadiums. One of the largest and most important stadium is the Dragon Stadium belonging to FCP- Futebol Clube do Porto, with a capacity of 51 000 and a roof covered area of 34 233 m2. The main design options for the roof and stand structures are presented in this paper. Some of the particular issues about large span roofs were considered, like dynamic behaviour under wind loads and erection schemes. The roof steel structure weighs 110 kg/m2 is made of plate girders and have a natural fundamental frequency of 1,123 Hz. The evaluated maximum vertical deflection under extreme wind action was 132 mm. An approach to the structural performance under crowd loading, particularly the dynamic response of the stands’ structures was made; a good performance of the structure was confirmed by monitoring during two events.
