Title: Vibration monitoring of a grandstand in Dragon Stadium
Issue Date: 2007
Abstract: The present communication focuses on the importance of the dynamic actions inducedby groups of people with synchronous movements and the need to perform dynamicanalysis in the corresponding structural elements. Special attention herein is given to the case ofstadium structures.The continuous optimization in structural design made possible, in certain cases, to resist to highloading values in ultimate limit states but still have serviceability deficiencies. Problems withexcessive vibration on recently built structures have been reported (SCOSS 2001). This cancause human discomfort, crowd panic or collapse of the structure.Simple methods like adopting a frequency threshold cannot always be applied since they mayresult in a substantial increment in cost or are impossible to accomplish due to architectural constraints.This is the reason why it is unavoidably necessary to model and evaluate the dynamicresponse of certain structures.This article presents also some results of the monitoring of two events in a grandstand onDragon Stadium in operating conditions.
