The Structural Engineer, Volume 75, Issue 22, 1997
Since March this year, BRE has been operating in the private sector - a major change after 76 years as a Government or Government-funded organisation. R.M.C. Driscoll
This paper reviews various aspects of dynamic excitation of stadium structures by spectator activity. A historical review of relevant research and testing relating to the magnitude of forces generated by people involved in coordinated activity is outlined, together with data relating to the requirements of various Codes of Practice. The theory relating to the prediction of structural response to spectator jumping is presented, and a method for carrying out analyses is detailed. The paper considers a number of common stadium structures and discusses features which are potentially vulnerable to dynamic excitation. Finally, the paper gives examples where natural frequency predictions have been compared with the results obtained from monitoring of completed structures. W.M. Reid, J.F. Dickie and Professor J. Wright
Dr J. R. Eyre (University College London) I am always interested in finding out more about the learning processes in young engineers. And let me say that I applaud anyone who makes contributions to this field as is being done tonight - not only because we all need to learn from it but because the valiant put themselves at great risk where so many others think that they know all the answers. You may think from this that I fit into this latter category.
