    An Application of Relative Entropy in Structural Safety Analysis of Elastoplastic Beam under Fire Conditions by Marcin Kamiński, Michał Strąkowski

    Published 2022-12-01
    “…The probabilistic structural response is found here using hybrid computational technique–the Finite Element Method system ABAQUS with its fully coupled thermo-elastic analysis with 3D solid elements and probabilistic modules implemented in the computer algebra system MAPLE. The probabilistic response is determined via a triple stochastic analysis, which is based on the classical Monte-Carlo simulation, iterative generalized stochastic perturbation technique, and also using semi-analytical probabilistic calculus. …”
