Vibration Control of Spatial Structures using Spatially Dispersed Arranged TMDs

Abstract

The main objective of this research is to develop the vibration control systems for large span structures using spatially dispersed arranged TMDs (tuned mass dampers). When applying this method, we should consider the arrangements and design parameters of plural TMDs by different method using the usual single TMD. First, focusing on the issue of set-up of design parameters, the effects of the systems using single TMD and two existing methods of MTMD (multiple TMD) are analytically compared by using an arch model. The results show that the determination of the bandwidth of MTMD is very important. Next, we propose the arranging method of plural TMDs using MTMD and compare the proposed method with generally used method using single TMD.
