Active control of vibration of large span structures by controlling force in tendon

Abstract

Along with the development of the current construction science and technology, as the construction structures are built higher and higher, the spans is larger and larger, the problem of controlling the vibration of those structures will become more urgent during the calculation process. Within the scope of the article, the author will mention the method of active vibration control for the large span beam by controlling tendon (form of cable force transmission mechanism), arranged outside the beam’s cross section, to adjust the vibration of beam. The author applied the Simulink-Matlab 2017b program to simulate the vibration control diagram of the large span beam by adjusting tension force in the tendon and compared this vibration control method using this form with the vibration control by using the spring (form of spring-like force transmission mechanism), thereby showing the excellence advantage in vibration control efficiency as well as the feasibility of actively controlling the vibration of the large span structures by controlling tendon.
