Overview: An undamped natural frequency analysis of the roof of Chelsea Football Club's West Stand was performed by Whitby Bird & Partners using LUSAS Civil & Structural. The roof features one meter deep cell form beams supported by a 105m truss. The LUSAS analysis predicted more than 100 separate frequencies (eigen values) below a frequency of 5Hz. Further LUSAS analysis concentrated on the 15 separate modes of vibration below 1Hz and these results were compared with results from a wind tunnel test on a 1:250 scale model of the proposed roof at Bristol University's Department of Aerospace Engineering.
