Grandstands used for pop concerts - the interaction between mechanics concepts and structural problems

Dr T. Ji
UMIST


Grandstands are built for sports events, but they may also be used for pop concerts nowadays in order to meet public requirements and to generate new revenue. The dynamic loads induced by crowds at pop concerts can be significant and resonance is likely to occur at these events. The safety of grandstands used for pop concerts is of a practical and important issue in engineering design.

This talk will summarise the current understanding and some research work on dynamics problems in the design of grandstands. Theoretical and experimental investigations have been conducted on human actions on structures, on the dynamic behaviour of permanent and temporary grandstands and on grandstand response to crowd loading. The talk will emphasise on the interaction between mechanics concepts and structural problems in this investigation. New mechanics concepts have been abstracted from practical structural problems and one of them may lead to establishing a new subject. On the other hand, new methods, which are developed based on these concepts, are applied to designing for safety of grandstands and to solving other problems. Some of the applications may have impact beyond the traditional boundaries of Structural Engineering.
