Abstract

Abstract:

The vibration of three dimensional frame structures is studied as wave motion. A travelling wave model is constructed for passive damping vibration reduction. Two ways of passive damping, damping elements and damping joints, are studied, and an iterative approach to select damping positions is proposed based on the results of wave analysis. The results show that the travelling wave model is very suitable for local modification and analysis of structures.

Key words: travelling wave, structure vibration, damping
