초록

Recently, the trend in structural analysis and design is moving towards the development of reliable system. The reliability-based method defines variouslimit states related to usability and failure, thereby enabling multiple levels of design according to the importance of a structure. Meanwhile, an actualstructure is composed of a set of several elements, and particularly, a frame type is composed of a system in which the members are connected eachother. At this time, the actual connection between members is in a semi-rigid condition, not in complete rigid or hinged. This semi-rigid is found inseveral structures, especially in agricultural facilities designed with lightweight materials. In this study, a system reliability analysis technique for framestructure was established, and applied to an analysis of the semi-rigid connection. Various conditions of correlation were applied to reflect theconnectivity between members, and through this, the limitations of existing structural analysis method and the behavioral characteristics of structure wereanalyzed. The failure probability of the frame member component and the overall structure system was significantly different in consideration of thesemi-rigid connection. In addition, it was evaluated that the behavior of structure can be more accurately analyzed if the correlation according to theposition of members in a system is further investigated.

Abstract

Recently, the trend in structural analysis and design is moving towards the development of reliable system. The reliability-based method defines variouslimit states related to usability and failure, thereby enabling multiple levels of design according to the importance of a structure. Meanwhile, an actualstructure is composed of a set of several elements, and particularly, a frame type is composed of a system in which the members are connected eachother. At this time, the actual connection between members is in a semi-rigid condition, not in complete rigid or hinged. This semi-rigid is found inseveral structures, especially in agricultural facilities designed with lightweight materials. In this study, a system reliability analysis technique for framestructure was established, and applied to an analysis of the semi-rigid connection. Various conditions of correlation were applied to reflect theconnectivity between members, and through this, the limitations of existing structural analysis method and the behavioral characteristics of structure wereanalyzed. The failure probability of the frame member component and the overall structure system was significantly different in consideration of thesemi-rigid connection. In addition, it was evaluated that the behavior of structure can be more accurately analyzed if the correlation according to theposition of members in a system is further investigated.
