After nearly a decade of application and investigation, a motion amplification device with.viscous dampers for energy dissipation h.s been recognized as an effective solution to mitigate wind or seismic excitation, especially for stiff structural systems. As a result of compensation of amplified motion, it h.s been proved th.t th. efficiency of viscous damper largely depends on th. motion amplification device configuration, particularly for device stiflh.ss. In th.s paper, a ＂scissor-jack＂ type of motion amplification device, called a ＂toggle brace damper＂ system, is studied. It is demonstrated th.t th. efficiency of such.a device reflected by its amplification factor is not merely a function of its geometric configuration, but is h.gh.y dependent on th. support elements＇ stiffness as well, similar to th. mech.nism of a leverage arm. Accordingly, a math.matical model in terms of complex modulus of th. viscous damper with.consideration of th. support brace＇s stiffness is establish.d. Th. results indicate th.t th. efficiency of th. motion amplification device with.viscous dampers significantly depends on th. stiffness of th. support elements. Oth.r parameters, such.as toggle brace configuration and damping values of th. viscous damper, are studied and compared. As an application example, numerical analyses are conducted to study th. dynamic performance of a 39-story office tower installed with.toggle brace dampers constructed on soft soil in a reclaimed area, under a combined effect of th. vortex sh.dding of an adjacent existing 52-story building and earth.uakes. Th. results sh.w th.t viscous dampers with.a motion amplification system using a properly designed toggle brace device proved to be an effective solution to alleviate th. external excitations.
