摘要: A semianalytical quasilinear method based on the describing function formulation is proposed for harmonic response analysis of structures with symmetrical nonlinearities. The equations motion are converted to a set nonlinear algebraic equations. linear and parts structure dealt separately, former being represented by constant receptance matrix, latter generalized matrix which updated at each iteration. Several examples dealing cubic stiffness, piecewise coulomb friction type nonlinearities presented
