Abstract

The main objective of this research is to develop the vibration control procedure of several modes for large span structures using spatially distributed MTMDs (multiple tuned mass dampers). We have already proposed the set-up procedure for design parameters and the spatial arrangement of MTMDs to control various vibration modes effectively. In this paper, we studied analytically the influence of division number of MTMDs on the vibration control performance using a spherical shaped spatial structure. As a consequence, we could recognize that increase of division number tends to improve the control performance of the over all structure. And we considered the reason from the point of variation of equivalent mass that is an important parameter to design the multi-degree-of freedom system.
