Original Abstract

The paper deals with the seismic linear response spectrum modification based on a probabilistic approach. The modification improves the correctness of the deterministic seismic analysis of building structures using the response spectrum method. In that case, the structure response depends strongly on computed natural frequencies. The proposed response spectrum modification accounts for uncertainties in response due to uncertainties in frequencies caused by variances of computation model parameters. The response spectrum is modified so, that with a selected probability the given spectral values should not be exceeded. The variance of natural frequency values is obtained by modal analysis of a stochastic model of the structure.

Keywords
