The main objective of this research is to develop the vibration control system for large span structures using distributed MTMD(multiple tuned mass damper) method. In this paper, we extended existing MTMD method proposed for controlling one mode into controlling several modes and proposed the configuration of MTMDs which were arranged at maximum displacement points of a superposed shape of controlling modes. First, the analytical result using a basic model show the proposed configuration of MTMDs is almost equal to the result obtained by a sequentially optimizing program. Next, we analytically compared the effect of vibration control of the conventional single TMD method and the proposed MTMD method using a 50m span single layer lattice shell model. From the obtained results, it could be concluded that in the case of the single TMD method the nonuniformness of responses of whole parts was very large, but in the case of MTMD method the responses of whole parts were controlled very effectively.
