The Research Situation and Prospect of the Structural Vibration Control

Abstract

Vibration control technology has a broad application prospect in the civil engineering anti- seismic. It can be used to reduce the vibration response of structures under the dynamic loads, such as earthquake and wind, and also be used to improve the structure vibration resistance and extend the fatigue life of structure. This paper expounds the basic concept and principle of passive control, active control, semi-active control and hybrid control in structural vibration control, the comparison and analysis between them and the advantages and disadvantages of the various control methods for structure, and mainly analyzes the various form of passive control. At last the author looks forward to the development prospects and development direction of the structure vibration control theory, and indicates the direction for future research.
