Abstract (EN):
The present communication focuses on the importance of the dynamic actions induced
by groups of people with synchronous movements and the need to perform dynamic
analysis in the corresponding structural elements. Special attention herein is given to the case of
stadium structures.
The continuous optimization in structural design made possible, in certain cases, to resist to high
loading values in ultimate limit states but still have serviceability deficiencies. Problems with
excessive vibration on recently built structures have been reported (SCOSS 2001). This can
cause human discomfort, crowd panic or collapse of the structure.
Simple methods like adopting a frequency threshold cannot always be applied since they may
result 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 dynamic
response of certain structures.
This article presents also some results of the monitoring of two events in a grandstand on
Dragon Stadium in operating conditions.
