The structural design should accurately reflect the code requirements in the construction drawings and consider the convenience of the construction. Some problems in the design of the confined boundary members in shear walls were discussed. Referring to the force principle and code requirements, feasible solutions are given.Keywords: boundary member; transverse reinforcement ratio; longitudinal reinforcement; stirrup; spacing参考文献[1]GB 50011—2010 建筑抗震设计规范[S].北京:中国建筑工业出版社,2010.[2]JGJ 3—2010高层建筑混凝土结构技术规程[S]. 北京:中国建筑工业出版社,2011.[3]11G101-1混凝土结构施工图平面整体表示方法制图规则和构造详图[S]. 北京:中国计划出版社,2011.[4]11G329-1建筑物抗震构造详图(多层和高层钢筋混凝土房屋)[S]. 北京:中国计划出版社,2011.[5]GB 50010—2010混凝土结构设计规范[S]. 北京:中国建筑工业出版社,2011.
