An Experimental Study Focused to Spectators-Induced Vibrations of a Cantilever Grandstand During Two Sport Matches

Popis výsledku v původním jazyce

Synchronize movement of a larger spectator group on a sport stadium (like as jumping, bouncing, jouncing, swaying or abruptly rising) can generate a significant dynamic load of a grandstand and induce subsequently its discomforting vibrations. The largevibrations are detectable even visually in some extreme cases. The excessive grandstand vibrations may initiate a panic, a subsequent stampede and a crush resulting in injuries even in deaths of spectators. History shows that large vibrations of a grandstand could cause its collapse in a special situation. A dynamic experiment that is described in the paper was realized on a steel cantilever grandstand during two football matches in the area where the most active spectators were concentrated. Vertical accelerations were observed at the ends of three grandstand main beams. Vibrations which could be perceived by spectators as uncomfortable were detected in some special situations (scoring of a goal and fans celebration after the end of th
