Damped modal analysis of full base isolation
Damped modal analysis based on a new developed quadratic eigenvalue solver is presented. Its special feature is the capability to analyse the free vibration mode of a multi-degree-of-freedom system as a function of the variable physical damping attached to the system at its nodes. The noval 'Modal Flow Analysis' is a helpful tool to control the structural behaviour independently from the excitation. However for each excitation and desired damping value the modal integration can be performed. The method is applied to analyze the base isolation of the reactor building supported on helical springs and damper elements.
