The roofing has been equipped with 252 pressure taps, of which 126 at the
extrados and 126 at the intrados, in order to get the net pressures on the roofing. In
the model the roofing of the stadium (Fig. 12) has a box structure in order to allow
for the settlement of the pressure taps inside.A minimum thickness of about 7 mm
has been required for the roofing structure to allow for the insertion of the pneumatic
