Serviceability assessment of two different stadium grandstand during different events

Abstract

This work presents an analysis of the measured vibration levels during different events on two different grandstands of the Milano stadium (Giuseppe Meazza). The stands vibration is nowadays measured 24 h a day all year long, providing a huge quantity of data coming from ambient vibration, football matches and live rock concerts. A part of these data, the one gathered during different events, is here analyzed according to international standards and recognized national guidance in order to assess the stadium serviceability against people induced vibrations during different events and to critically face the limits imposed by the standards. The analysis also puts into evidence how the different dynamic properties of the selected stands affect the measured vibration levels and how concerts and football matches provide a totally different excitation source.
