Abstract
This paper propose the mechanism using lever and attached weight at point of action of lever, installed horizontally in the space between two floor slabs for the purpose of seismic response control of a high-rise building. This mechanism produces the dynamic mass related to the relative displacement between two slabs. The generated dynamic mass is shown to be effectiveness for the seismic response control of building from the point of view of the enlarged mass ratio of tuned mass damper to mass of high-rise building.
