000005021 520__ $$2eng$$aA method is proposed to build a sparse polynomial chaos (PC) expansion of a mechanical model whose input parameters are random. In this respect, an adaptive algorithm is described for automatically detecting the significant coefficients of the PC expansion. The latter can thus be computed by means of a relatively small number of possibly costly model evaluations, using a non intrusive regression scheme. The method is illustrated by a simple polynomial model as well as the example of the reliability of a frame structure.
