This paper presents formulation for the non-stationary response of a Du$ng oscillator under a seismic excitation process. The excitation process is assumed to be characterized through wavelet coe$cients and the non-linear system is replaced by a stochastic equivalent linear system with time-varying

In this study, an undamped Du$ng's oscillator equation with time-dependent parameters has been considered. The time-varying part is expanded in a series of ultraspherical polynomials in the spirit of Sinha and Chou and only the constant part is retained. The non-linearity parameter is assumed to be
This paper presents an analytical approach based on the power series method for determining the periodic solutions of the forced undamped Duffing's oscillator. The time variable is first transformed into a new harmonically oscillating time which transforms the governing differential equation into a
