Nonlinear Wave Propagation in Complex Structures Modelled by Random Media with Self-Stresses,calisation and parameter uncertainty, complex structures are modelled by random media with self-stresses, the role of the latter being played by the internal degrees of freedom of structural members. The rheological model is composed of an infinite number of elastic-plastic elements in parallel. The

Spectral Response of a Beam-Stop System Under Random Excitation,ing with stiffness depending on the amplitude of the deflection at the impact location. Performing the expectation of the spectral density function of the linear system with respect to the probability density of the response amplitude (assumed to be a random variable), an estimate of the nonlinear r

Extension of The Stochastic Differential Calculus To Complex Processes,elope function, which is the modulus of a complex process, is usually introduced. In this paper the statistics of the complex response process related to the envelope statistics of linear systems subjected to parametric stationary normal white noise input are evaluated by using extensively the prope

Response of a Hysteretic System Under Non-Stationary Earthquake Excitations,tic behavior in which the restoring force depends not only on the instantaneous deformation, but also the past history of the deformation. Consider an engineering structure idealized as a single-degree-of-freedom system governed by.where ξ.(.) are ground accelerations, and . is a hysteretic restorin

Viscoplastic Responses With Stochastic Q-Damping Or Soil,lems, energy loss per cycle generally varies with the frequency of excitation. In a large number of geophysical computations, however, frequency .. — a higher value of Q indicating less damping — are routinely chosen for convenient representation of soil damping characteristics in the visco-plastic
