In the open literature, there are books on statistical dynamics of structures and books on structural dynamics with chapters dealing with random response analysis. However, a systematic treatment of stochastic structural dynamics applying the finite element methods seems to be lacking. Aimed at advanced and specialist levels, the author presents and illustrates direct integration methods for analyzing the statistics of the response of structures to stochastic loads. The analysis methods are based on structural models represented via the Finite Element Method. In addition to stationary linear problems the text also addresses non-stationary excitation and systems with spatially stochastic property variations"--$cProvided by publisher. 606 $aStructural dynamics$xMathematics 606 $aFinite element method 606 $aStochastic analysis 615 0$aStructural dynamics$xMathematics. 615 0$aFinite element method. 615 0$aStochastic analysis. 676 $a624.1/70151922 686 $aMAT034000$2bisacsh 700 $aTo$b Cho W.
