Vibration Analysis for retractable roof movement of Spatial Structure

Retractable roof system of stadium or complex structure indicates a special feature of spatial structure well. As like moving load, impact load, inertial or braking loads, these dynamic loads induced by the retractable roof movements are loaded to spatial structure. So it is necessary to analysis of spatial structures are subjected to these dynamic loads. Dynamic loads that are induced by the retractable roof movements can be applied to moving mass method or moving force method. But, moving force method is appropriate because the retractable roof movement is slow relatively. In this paper, vibration analysis of spatial structures is executed by using equivalent moving force. This proposed equivalent moving force can be effectively applied to spatial structure that is subjected to dynamic loads induced by movement of the retractable roof system. So, serviceability and safety check of spatial structure with retractable roof system is possible.
