A set of reduced models of structures and wind loads is proposed for a high-rise building under time-dependent wind loading. A reduced structural model is constructed first based on an inverse problem formulation in terms of fundamental eigenfrequency and eigenmode. Then a reduced model of time-dependent wind loads is proposed by requiring the equivalence of displacements at representative nodes in the frame model and the reduced model without inertial and damping terms. These reduced models are applied to both the bare frame and the frame with high hardness rubber dampers. The validity of the proposed reduced models is investigated by the comparison with the results by the time-history analysis for an original full model.
