FATIGUE CALCULATION ON THE ROOF SUSTAINING CABLES OF A LARGE STADIUM IN PARIS

Wind loading on the roof of a large stadium, ''le grand Stade'', in Pa ris, has been measured in a boundary layer wind tunnel using a 1 to 20 0 scaled plexiglas model equipped with 191 pressure taps. The spectrum of the integrated force shows a non-negligible part in the frequency domain of the first seven eigen modes of the structure and the instant aneous stress in some stays has been calculated including the dynamic participation of these modes into wind excitation. Stress cycles have then been counted for some stays and extrapolated to a 50 yr period us ing meteorological data. These cycle number tables have been compared with the fatigue data tables of the stays to calculate their cumulated damage.
