Abstract
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. 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. In this paper we evaluate the influence of wind direction by plotting the wind-induced responses of analytical models and residual deformation of isolation layer.
