INFLUENCE OF ACCELERATION FIELD INHOMOGENEITY ON THE RESPONSE SPECTRUM.

The influence of the field of accelerations inhomogeneity on the building site on the structure response spectrum has been consider. For this aim, we used the identity coefficient of two signals, introduced earlier by the authors this paper, and including indicators of non-synchronous, incoherence and multiscale processes. Its note, that the true values the identity coefficients of vibration points of ground base of building site it is necessary to take into account when setting the seismic excitation. In the case of structure resonant vibrations, the incoherence of the seismic input of different points is more important.
