โœฆ Synopsis

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 parameters. An example ground motion process has been used to show that the proposed approach gives accurate response estimates in case of mildly non-linear systems.

The response of Du$ng oscillator to combined deterministic harmonic and random excitation is investigated. The method of harmonic balance and the method of stochastic averaging are used to determine the response of the system. Theoretical analyses and numerical simulations show that when the intensi

A formulation has been proposed for the transfer function of a secondary system response while the primary system is supported on a compliant soil and the excitation comprises of translational ground motion at its base. For this purpose, the earlier formulation of the authors for the fixed-base case
