In this paper, a new method for the identification and simulation of non-Gaussian and non-stationary stochastic fields given a database is proposed. It is based on two successive biorthogonal decompositions aiming at representing spatio–temporal stochastic fields. The proposed double expansion allows to build the model even in the case of large-size problems by separating the time, space and random...
The stochastic response to earthquake motion of flexible multi-storey shear type buildings isolated by rolling rods with a re-centering device is investigated. The re-centering device in the form of a spring or cantilever beam attached to the base of the structure reduces the rolling base displacement and returns the system to its original position after the earthquake. The stochastic model of the...
