Abstract: Experience shows that buildings with irregularities are prone to severe damage from earthquakes, as observed in many past events. This technical report presents a study of irregular structures near collapse and the development of an experimental model to study many types of structural systems in the near collapse state. The study shows that a separation of lateral and gravity load resisting systems can produce a stable structure in cases of major damage to the lateral system, provided that redundancy exists to control lateral deformations. Lists of illustrations and tables are included, along with an appendix and references.
