摘　　要：在高层建筑混凝土结构设计中,剪力墙连梁很容易发生超限现象。讨论了连梁定义、联肢剪力墙破坏形态和连梁设计原则,结合工程经验和规范要求对连梁超限问题从结构概念设计和结构构件设计两大方面考虑提出众多可操作的处理方法。建议:当梁宽小于等于200 mm时,设置钢板或设置水平缝;当梁宽不小于250 mm时,设置交叉斜筋或型钢混凝土梁;当梁宽不小于400 mm时,采用对角斜筋配筋或对角暗撑配筋。In the design of the concrete structure of the high-rise building,shear wall coupling beams are prone to out of the codes.To solve these problems,according to engineering experience and code requirements,some operational approaches were proposed.Suggest that if the beam width is less than or equal to 200 mm,setting steel plate or horizontal seam;if the beam width is not less than 250 mm,providing cross inclined bars or steel concrete beams;if the beam width is more than 400 mm,using diagonal bar reinforcement or diagonal brace reinforcement.Meanwhile,the definition of the coupling beam,the failure modes of coupled shear wall and the design philosophy of coupling beam were discussed in this paper too.
