AbstractVibration measurements have been taken in a sports arena during a 3 h rock concert to determine the effect of audience response on the dynamic behaviour of a stand area having a fundamental frequency below 5 Hz. The stand area, consisting of precast, prestressed concrete beams, was subjected to intervals of foot stamping and hand clapping at repetition frequencies between 2 and 3 Hz. Amplitudes of the resulting resonant and near-resonant behaviour are presented; dynamic live loads are calculated and together with static live loads are compared with design loads specified in the National Building Code of Canada.
