The main objective of this research is to develop the vibration control procedure of several modes for large span structures using distributed MTMDs (multiple tuned mass dampers). In order to examine fundamental and real behavior of the MTMD procedure, shaking table tests with a small-scaled arch model are executed. Firstly, to confirm frequency response characteristics of the MTMD procedure, tests using harmonic excitation are executed and we compare test results with analytical results. Then, we study controlling performance of the MTMD procedure under random excitation. Finally, we study robust performance of the MTMD procedure against frequency changes of structures that is important issue for real applications of the proposed method to the vibration control of several modes at a time.
