In recent years, the investigation into the damping performance of hybrid damping devices has garnered significant attention, particularly a hybrid damper composed of a tuned mass damper (TMD), and an inerter has been favored for their superior damping capabilities. In the work, novel solutions for spectral moments of wind-induced responses of high-rise structures with tuned parallel inerter mass system (TPIMS) were proposed. Additionally, an optimization method for TPIMS's parameters was presented, considering various structural responses to evaluate dynamic reliability and comfort. First, based on dynamic finite element technique, we established a comprehensive dynamic equation for high-rise structures integrated with TPIMS, addressing the challenge of obtaining mass and stiffness matrices in traditional dynamic equations. Second, using quadratic decomposition method for power spectrum density function and Gauss-Jacobi integration method, concise unified closed-form solutions of zero-, first-, and second-order spectral moments (ZFS-OSMs) of outputs were deduced. Third, leveraging the proposed ZFS-OSMs solutions, we applied Vanmarcke's method to optimize TPIMS parameters for enhanced dynamic reliability and comfort. Finally, three case studies were presented: one validating the proposed ZFS-OSMs solutions, another examining the influence of real vibration modes on calculation accuracy, and a third demonstrating the efficacy of the TPIMS parameter optimization method. The results indicate that the selection of real mode shapes must be tailored to the analyzed output, rather than assuming a small number of modes suffices. The proposed optimization approach comprehensively considers multiple responses from high-rise structures, offering valuable insights applicable to the analysis of other passive dampers.
