The IUTAM Symposium on Probabilistic Methods in the Mechanics of Solids and Structures, dedicated to the memory of Waloddi Weibull, was held in Stockholm, Sweden, June 19-21, 1984, on the initiative of the Swedish National Committee for Mech anics and the Aeronautical Research Institute of Sweden, FFA. The purpose of the symposium was to bring together mathema ticians that develop the theory of stochastic processes and methods for reliability analysis, with engineers that apply these theories and methods to model loads, strengths and structures for the advancement of structural safety. Waloddi Weibull was a pioneer in this field with his many publi cations from the thirties until his death in 1979. He also took an active part in the formation of the International Union of Theoretical and Applied Mechanics during the forties, and subsequently initiated foundation of the Swedish National Committee for Mechanics, through which Sweden joined IUTAM as a member. 116 participants from 21 countries attended the symposium, and 55 invited papers were presented in 7 scientific sessions.
