摘　　要：分析了墙体内水平钢筋最小配筋率与块体、砂浆强度等级、钢种以及竖向压应力之间的关系,得出了正常使用阶段水平钢筋最小配筋率的变化范围,与现行规范规定基本吻合;同时提出了设计时墙体呈延性剪切破坏所需的水平钢筋最小配筋率简化计算公式以及水平钢筋用量最省时竖向压应力控制范围,可供设计时参考.The relations between the minimum horizontal reinforcement ratio of wall with strength grade of block,mortar,reinforcement and vertical compressive stress were analyzed on the basis of research results abroad.The variant scope of minimum horizontal reinforcement ratio during normal service was derived.It coincides with the current code stipulation.Simplified formula of minimum horizontal reinforcement ratio for wall with ductile shear failure has been provided.At the same time,vertical compressive stress dominant scope is proposed when minimum horizontal reinforcement is needed.This research result can be used as a reference in design.
