摘要:The paper presents comparison of the fans´ behaviour on two football stadia in Prague, stadium of AC Sparta Praha and stadium of SK Slavia Praha. The behaviour of fans was monitored by camera and classified to different categories. The response (acceleration) of the grandstands was measured on both stadia at the most exposed positions. The comparison of the response of two grandstands with different bearing systems (a steel cantilevered structure and a reinforced concrete frame structure) induced by fans is presented and discussed in the conclusion.
