Coupling beams between openings are the main plastic energy dissipation elements of coupled walls , but whether short coupling beams could ensure that shear failure would n ' t take place before coupling beams have reached certain displacement ductility or not , is still a problem of engineering which has n ' t been solved and is one of the critical problem of the code for design of concrete structures which remains to be solved 洞口连系梁是联肢剪力墙的主要塑性耗能构件，但跨高比较小的连梁是否能保证在达到一定的位移延性之前不出现剪切失效，仍是目前我国工程界未解决好的问题，也是我国《混凝土结构设计规范》遗留下来有待解决的关键问题之一。
In this paper , there are three main purposes to be attained . firstly , enough ductility of coupling beams is needed , namely no shear failure occurs too early . secondly , the capacity of energy dissipation is satisfied on the grounds of enough stiffness 本文的主要研究目的是首先保证连梁具有足够的延性，即保证连梁端部在达到较大弯矩之前，不过早发生剪切破坏；其次是在保证剪力墙整体强度的前提下，连梁还需具有良好的耗能性能；连梁的配筋构造不太复杂，方便施工。
