Abstract
    This paper describes probabilistic characteristics of damping in a tall building based on the results of full-scale measurement. It is found, through statistical analysis of the damping data, that the probability density function(PDF) of damping at the high amplitude plateau can be well represented by Normal distribution ( Gaussian distribution). A stochastic damping model is proposed to estimate amplitude-dependent damping for practical application.
 
Key Words
    damping; tall building; full-scale measurement.
