heal.abstract	The efficient prediction of the stochastic dynamic response and reliability of structures with uncertain system properties poses a major challenge in the field of computational stochastic mechan-ics. In the framework of the stochastic finite element method, an efficient approach has been recently introduced by the authors for the analysis of realistic structures subjected to transient seismic actions. This approach is used here to assess the reliability of a steel frame modeled with a mixed fiber-based beam-column element. The uncertain parameters of the problem are the stiffness and strength, both described by homogeneous non-Gaussian translation stochastic fields. The frame is subjected to natural seismic records corresponding to three levels of increasing seismic intensity. Parametric investigations are carried out providing useful conclusions regarding the influence of the correlation structure, correlation scale and discretization of the stochastic fields on the response variability and reliability. © 2011 Taylor & Francis Group, London.	en
