Seismic isolation system proves to be efficient in reducing the seismic response of a building. With the increasing number of base-isolated high-rise buildings, the wind effect cannot be neglected. However, only a few people have set foot in the wind-resistant design of base-isolated high-rise buildings. Strong wind may bring about continuous and violent vibration of the flexible isolation layer, leading to the fatigue damage of steel dampers that were installed in the seismic isolation layer. Thus, fatigue damage evaluation is of critical importance to damper performance in the practical design. Previous study aims to investigate the wind-induced response characteristic of the 20-story high-rise seismic isolated steel building constructed at Tokyo Institute of Technology based on the observed records. This current paper focuses on investigating the fatigue damage by means of typhoon simulation. Variations in the fatigue damage degree are observed, and they are summarized according to different cases of wind direction. The authors also evaluate the influence of wind direction by plotting the wind-induced responses of analytical models and residual deformation of isolation layer.
