Dynamic pulley damper system (DPDS) as an innovative methodology for a response control system using a block and tackle mechanism to provide enhanced vibration reduction in high-rise buildings, has been proposed. The key aspect of this system is to exponentially increase the damper movement using an amplification mechanism comprising movable pulleys and a wire. This paper presents the relation between the arrangement of the wire’s angles, particularly in the amplification part, and the vibration reduction effect. The DPDS is introduced into a center-core high-rise building. Two small building varieties with different core heights are designed; then, a wire is stretched between the frame and the core structures. The capability of the DPDS to control vibration is confirmed via the shaking table test. Additionally, the accuracy of the simulation models is verified by a comparison with the experimental results. Moreover, this paper includes a parametric analysis test to determine the wire-stretching angle for establishing the most efficient design. The results of the above analysis show that the wire-stretching angle influences the seismic performance of the DPDS.
