"In this experimental study, the influence of the high intensity dynamic cyclic loading on the change of the modal characteristics of the prestressed concrete slab was monitored. The cyclic load was applied to the slab in several steps. Before the test and after each load step the dynamic response of the slab was measured Modal characteristics of the slab, which were measured after each load step, were mutually compared. Changes of natural frequencies f(j) of the slab were computed first. For the comparison of natural modes, changes of a mode surface curvature CAMOSUC(j),x, changes of a modal flexibility matrix [] and the second derivative of changes of diagonal members of a modal flexibility matrix [] were used." . .
