SIMPLE JUDGEMENT OF FAILURE MODE AND SAFE STATE OF COUPLING BEAMS
-
摘要: 作为剪力墙结构中的主要耗能构件,连梁在剪力墙的抗震性能研究中占有重要地位,对连梁破坏状态的研究就显得十分重要。归纳了连梁的4种破坏模式,提出简化公式分别根据连梁的耦联率和连梁的破坏形式区分模式,并判断连梁的安全状态。Abstract: As a energy-dissipation member of coupled shear wall,the structural behavior of reinforced concrete coupled shear wall is greatly influenced by the behavior of their coupled beams. The failure mode of coupling beam is important in the study of shear wall. It is introduced four kinds of failure modes of coupled wall,and the reduced formula to judge the failure mode and safe state.
