Abstract

Stadia structures, like the G. Meazza in Milano, nowadays host many events that they were not originally designed for. Apart from the traditional football matches many live rock concerts and other public happenings are hosted. In this paper a comparison is made in order to classify the different kind of events in terms of vibration serviceability assessment measurements. The reached vibration levels must be evaluated against the serviceability levels given in existing guidance in order to prevent dangerous situations, such as panic or other uncontrollable phenomena in the crowd. Standards exist to evaluate vibration levels, among them the most widely used are ISO2631-1, ISO2631-2 and BS6841, which differ in the frequency weighting used and in the quantities used to identify the vibration, even though the starting point is the same measured acceleration time histories. More than a comparison of the two standards, already discussed in other papers, this paper investigates the level reached during different events and the influence of all choices left free to the technician performing measurements. Standards are applied to a set of vibration measurements taken on different events on different parts of the G. Meazza stadium. Results are then compared to the reference values suggested in the standards and to the limits found in literature. The effect of the dynamic response of the different sub-structures of the stadium on the reached vibration levels is analyzed and a set of results are given in order to asses the validity of limits given both in the standards and in literature. © 2009 Society for Experimental Mechanics Inc.
