A seismic isolation system proves to be efficient in reducing the seismic responseof a building. With an increase in the number of base-isolated high-rise buildings, the wind effectcannot be neglected. However, only a few studies have focused on the wind-resistant design ofbase-isolated high-rise buildings. Strong winds may bring about continuous and violent vibrationsin the flexible isolation layer, leading to fatigue damage in the steel dampers installed in theseismic isolation layer. Thus, fatigue damage evaluation is of critical importance to damper performancein the practical wind-resistant design. This study investigates the fatigue damage byconducting typhoon simulation. Variations in the fatigue damage degree (D value) are observed,and are summarized according to the different aspect ratios of base-isolated high-rise buildings.In addition, an attempt has been made to explore the relationship between the average windspeed UH and the 10-minute fatigue damage degree (D10 value) to obtain prediction formulas aswell as plot the maximum wind-induced responses of the analytical models and the maximumdeformation of isolation layer before the evaluation of D values.
