Based on the time integral of the absolute ground velocity, a new index is defined, as the cumulative absolute displacement CAD. The index is used in order to evaluate the strong motion duration. The proposed bracketed-significant duration is well correlated with the strong motion part of the records, especially in the case of near-source events. The duration and the CAD index are correlated with the structural behaviour of medium-to-long period structures. Two normalized parameters representing the amplification of structural response and the number of equivalent loading cycles are determined in terms of the proposed duration and CAD indices. The proposed parameters appear to be better correlated with the structural response than other well-known indices.
