Abstract:
To check whether a structural system is proportionally damped in dynamic analysis, Caughey advanced criterion to examine if the generalized damping and stiffness matrices of the system commute. This criterion depends on the data of generalized damping which are not directly measurable. This is a sever restriction. In this paper, we present an alternative criterion to determine the proportionality of damping which is rigorous and dynamically flexible. In particular, it can be used in both forward and inverse problems.
