Seismic response records from the CSMIP database are used to formulate expressions for the expected value of damping ratios as a function of available regressors. The paper discusses the source of the high variance in the identification of damping and proposes mechanisms for the correlation between fundamental building frequency and damping as well as for the observation that damping increases with the mode number. The data analyzed is restricted to cases where the ground accelerations exceed 0… CONTINUE READING
