Abstract As buildings have become higher, it is likely to find the wind loads that is equal to or even greater than the desing seismic loads. Therefore, it is important to estimate responses of high-rise buildings under fluctuating wind force. This paper presents contribution rate of higher mode wind response of multi-mass system for high-rise buildings by using a modal analysis in elasto range. Then, it shows that the wind responses are usually separated into the low and high frequency components, and the wind responses can be expressed as sum of them. The agreement between the predicted value based on coupling of two components and results of time-history analysis was finally confirmed.
