The British band Coldplay closed on Saturday, 18/3, the cycle of six shows in São Paulo, part of the world tour “Music of the Spheres” that celebrates the last album of the group. For the safety of the musicians and thousands of fans who attended the concert, the Morumbi stadium was being monitored by IEME Brasil, which installed sensors to measure the deformation of the structure subjected to dynamic loads, such as those generated by the public jumping in music shows or in matches. of football. These measurements provide a number of important pieces of information about the structure.
Stadiums that are constantly monitored and receive regular maintenance, as is the case of Estádio Cicero Pompeu de Toledo (São Paulo Futebol Clube – SPFC stadium), are very safe. Unfortunately, most Brazilian stadiums do not have this concern. The problem can arise when the structure enters into resonance, that is, the frequency of the dynamic load coincides with the natural frequency of the structure. In these cases, vibrations can exceed the limits allowed in technical standards and cause public panic, accidents and even the collapse of the structure.
SPFC, always concerned with ensuring the safety and comfort of its public, once again hired IEME Brasil to monitor the structure of the stadium. This time the event was the Coldplay concert. Congratulations to the SPFC staff for their care and responsibility.
