The analysis of reliability is an important and active area of research in optimizing structural design and in improving structural safety. In order to determine the relationship between system reliability and reliability of its components, a reliability block diagram method which emphasizes the connection mode among all the components of a system is proposed. With the assumption of geometric stability and limited displacement at nodes, a new approach, aimed at determining key elements whose damage would lead to overall collapse of the structure, is adopted for the logic relationship identification among components. The logic relationship, which is regarded as the core component of the reliability block diagram, is utilized for the reliability analysis of the system and the predetermined components. A case of a specific cable dome is investigated to illustrate the modelling process of reliability block diagram. The results show that the reliability block diagram method is an effective approach for analyzing the reliability of the system and its associated components.
