Redundancy of Exodiagonal Building Structures

摘要

Exodiagonal building structures are defined as those having a regular series of intersecting diagonal members, completely or partially encompassing the building's exterior face, that carry both gravity and lateral loads. Exodiagonal building structures normally lack vertical members on the exterior walls. The highly redundant exodiagonal structural system facilitates the immediate redistribution of internal forces away from damaged portions of the shell in the case of an extreme loading event. Structures of this type are uniformly resilient without any inherent vulnerabilities. Several completed buildings utilizing this type of structural system are in use today around the world. The general performance characteristics of exodiagonal building structures with respect to redundancy are examined in this study.
