A Review of Recent Features and Improvements Added to FERUM Software
Résumé
The development of FERUM (Finite Element Reliability Using Matlab) as an open-source
Matlab® toolbox was initiated in 1999 under A. Der Kiureghian’s leadership at the University of California at
Berkeley (UCB). This general purpose structural reliability code was developed and maintained by T. Haukaas, with the contributions of many researchers at UCB. The present paper aims at presenting the main features and capabilities of a new version of this open-source code based on the main contribution of the first author and the help of a few Ph.D. students at the Institut Français de Mécanique Avancée (IFMA) in ClermontFerrand, France. The main concepts of FERUM are preserved and this paper lists the major changes operated
in this code. Available algorithms are briefly presented and, for some of them, they are applied on reference
examples for illustration purposes. This new version offers improved capabilities including simulation-based
technique (subset simulation), sensitivity analysis (Sobol’s indices) and a Reliability-Based Optimization algorithm. Beyond the new methods implemented in this code, this paper put some emphasis on the new architecture of the code, which now allow distributed computing, either virtually through vectorized calculations
within Matlab or for real with multi-processor computers.
