In this study, fatigue damage of LRB in base isolated building under wind load during review period is evaluated with employing result of anamnestic cyclic loading test. Frequency of displacement amplitude is calculated from time history of displacement using Rain Flow Method. In this model, fatigue damage of LRB in the corner of building is the largest from the effect of torsional component of wind force. Due to frequency of accumulated time in low wind speed range, responses in this range have a large effect on fatigue damage of LRB.
