Available response spectrum methods and paper. modal combination rules such as SRSS or CQC have been used for estimation of displacement demands but cannot be directly used for estimation of peak acceleration. A method has been developed based on absolute acceleration modal accelerations and ground acceleration. The proposed method are extensions to CQC method which not only considers the correlation between modal accelerations, but also takes into account the correlation between ground acceleration and modal accelerations. The formulation for estimation of peak floor a ration acceleration has been presented. Closed form solutions for correlations between the modal accelerations as well as modal accelerations and ground accelerations have been derived for filtered white noise inputs. Empirical equations for correlations between modal accelerations as well as modal acceleration and ground acceleration are presented. It odal is shown that the proposed method can capture the peak floor acceleration obtained from time history analysis. KEYRORDS: peak floor acceleration, response spectrum method, correlation, continuum model
