The structural reliability of tubular composite members

Abstract

An advantage and application of the concrete-filled steel tubes in construction practice is discussed. An urgency to investigate the structural performance and reliability of tubular composite structures is analysed. The robustness and structural safety of a new type of tubular members of annular cross-sections are considered. The time-dependent safety margin of members and its components as random resistance and action effect processes are presented. The survival probability analysis of members is based on the concepts of random sequences, conventional resistances and transformed conditional probabilities.
