In order to obtain the basic characteristics of the Random Decrement Technique, the numerical simulation of wind-induced vibration are conducted for single- and two-degree-of freedom systems with a given damping ratio. The effects of various parameters on the resultant damping ratio are examined, i. e. the number of superposition of samples, the value of the damping ratio, band width of band-pass filter and so on. The Random Decrement Technique is applied for evaluation of damping ratios of full-scale buildings. The results suggest that the technique is very useful for evaluation of the damping ratios of actual buildings under random excitations.
