    Abstract

    To improve seismic resilience and sustainability of structures, a pendulum-type nontraditional tuned mass damper (PNTTMD) system with re-centering mechanism is proposed for high-rise structures with nonnegligible bending deformation involved. This proposal is motivated by the self-centering behavior of structural components in ancient structures, for example, Greek tower or pagodas, with the assistance of gravity. Analytic formulae employing the stability maximization criterion for optimum design of the PNTTMD are derived, where the rotational angle of the roof is considered. Satisfactory vibration and damage control effects of the PNTTMD system are verified through experimental and numerical investigations.
