Abstract
In this study, we propose a system to reduce the displacement of the tuned mass damper (TMD) with lever and pendulum mechanism that was placed in the roof for seismic response control of high-rise buildings. This is a displacement magnifying mechanism attaching the weight and lever in the horizontal direction in the space between the roof and TMD. In particular, in thig paper, the optimal tuning method of the dynamic mass(D.M.) is examined, and by applying this control system to the single degree of freedom (SDOF) building and the multi-degree of freedom (MDOF) buildings as shown in Figs.l and 2 subjected long-period earthquake motions for response control, its effectiveness is examined
