STUDY ON DAMPING DISTRIBUTION OF MAXWELL-TYPE VISCOUS DAMPERS BASED ON EIGENVALUE ANALYSIS

Abstract

Eigenvalue analysis considering Maxwell model is proposed in this study, so as to compute properties and distribution of viscous dampers automatically. A real number eigenvalue of Maxwell model shows dynamic characteristic of viscous damper. If the real number eigenvalue becomes equal to a natural circular frequency of analysis model, the model will have the maximum energy dissipation to the vibration mode. In this paper, viscous damper distribution of a frame structure has been computed by the proposed method. The results have showed that the structure has the highest viscous damping factor to the design vibration mode.
