“…Thus, the frequency spectral method plays an important role in the PDM of wind‐induced responses and wind resistance design. Wind resistance design codes in many countries were developed by the frequency spectral method, such as Architectural Institute of Japan (AIJ) recommendations for loads on buildings (Japan Standard), 10 AS/NZS 1170.2 (Australian/New Zealand Standard), 28 ASCE 7–10 (the US Standard), 29 and so on. However, the frequency spectral method lacks considering the effect of the frequency dependency of structures, so it is uncertain to predict the wind‐induced responses of the frequency‐dependent structures, such as VE‐damped systems.…”

SummaryTime history analysis is sometimes used in an estimation of the wind‐induced response of a tall building. However, time history analysis for the wind‐induced behavior by the ensemble‐averaging wind force costs much computation time. This paper provides a reliable prediction method for the wind‐induced response of the viscoelastic (VE)‐damped system considering its frequency dependency coupling with frame damping effect with frequency spectral method. VE damper used in high‐rise buildings can dissipate energy from excessive vibration induced by seismic or wind excitation. Fractional derivative (FD) model of VE dampers can express VE frequency dependency clearly, but it is computationally complicated. The herein proposed prediction method is based on frequency spectral method and evaluated wind‐induced responses of the single degree of freedom (SDOF) VE‐damped system with a FD VE damper subjected to the respective 1st modal along‐ and across‐wind force. The maximum error of wind‐induced responses of the VE‐damped system, such as the root mean square value of responses, the total input energy, and the total energy dissipation, is within . In summary, the proposed method had high accuracy in the prediction of wind‐induced responses of the VE‐damped system considering its frequency dependency with the coupling effect of frame damping.
