The fast development of computational facilities and new computational methdologies allows the efficient implementation of stochastic structural analysis. Thus, a quantification of the probability of results of structural analyses in addition to pure deterministic prediction of their magnitudes is possible. Especially the evaluation of the reliability of structures expressed in terms of failure probabilities becomes feasible. To apply these methods in research as well as in industry, efficient programming concepts are necessary, i.e. convenient user interaction, modular prgramming, comprehensive macro language, etc. In this context, also a user-friendly possibility of applying parallel processing algorithms is described. These topics are exemplified by utilizing a concept denoted as COSSAN~(TM) (Computational Stochastic Structural Analysis).
