The influence of the model selection in the response analysis of high-rise buildings is quantitatively discussed from a probabilistic standpoint. Provided that a multi degree of freedom model is applied to the response analysis, we suppose that selection of the degree of freedom mainly identifies the selection of modeling. Furthermore, the uncertainty associated with the modeling is taken into analysis in terms of randomness of rigidity. Then quantitative discussion is performed on the effect of the model selection on probabilistic properties associated with the maximum response. Numerical results show that the model selection sensitively affects on the variance of the maximum response as well as the probability that the maximum response exceeds a critical level.
