Response of a Stadium to the 1999 Athens Earthquake

This paper deals with the effects of the Athens earthquake of 7 September 1999 on the bearing elements of the main construction of the "Peace and Friendship" Stadium (SEF from its name in Greek Stadio E rinis & Filias) in Neo Faliro, situated about 10 km from the city centre. The kinematic behaviour of the bearing frame of the main construction of the Stadium was monitored using geodetic methodology, for a long time (1986 to 1998) before the strong seismic shocks in September 1999. The survey of the concrete bearing elements of the Stadium is presented, a year after (2000) the earthquake, in order to detect the structure's response. Through this monitoring it was found that the concrete roof of the Stadium had moved. The vector of the displacement of the roof's centre is estimated and its direction (azimuth) is related with the earthquake's epicentre.
