Dynamic problems at accidental excitation
Abstract
The analysis of influence exerted on structures by seismic motion is presented in the paper. The analysis has pointed to the level of significance of correlations among modal forms, spectral density of response level, and the mean square value of structural response. It is demonstrated that this analysis is the way towards simplification of complex calculations that must currently be made to obtain response of a structure exposed to accidental seismic excitation, simulated by white noise.
