SAITO, Taiki. A new seismic response control technique for buildings using block and tackle. Tecnia [online]. 2019, vol.29, n.2, pp.11-21. ISSN 0375-7765.  http://dx.doi.org/10.21754/tecnia.v29i2.719.

The author proposed a new seismic response control system using a block and tackle (hereinafter, referred to as a dynamicpulley damper system) developed especially for the high-rise buildings. The proposed system has a configuration where adamper is installed on the track of the cable-stayed wire, amplifying the amount of movement of the wire by using a movablepulley that increases the damping effect to reduce the vibration of a building. we apply this system to connect the corestructure (parking tower) and the surrounding frame (housing part) of a high-rise building. This system aims to reduce theearthquake response of the building by the force of the damper attached to the core structure. To verify the effectivenessof this response control system, two types of shaking table tests were conducted; one is the large-scale shaking table testusing a magnetic damper, an-other one is the small-scale shaking table test using a steel damper. The mathematical modelof the dynamic pulley damper system to implement the frame analysis was developed and the results of simulation analysisare compared with the experiments.
