摘　　要：依据现行《混凝土结构设计规范》最大裂缝计算公式及其验算条件,推导出相关公式,编程计算出满足裂缝宽度要求的有效受拉区最小配筋率,并汇编成表格供直接计算满足裂缝宽度要求的配筋时查用.In accordance with The Code for Designing Concrete Structures and based on the formula for calculating maximum crack width, some formulas for computing minimum ratio of reinforcement to effective tensile region which satisfy the requirement of crack width are derived. A computation program has been developed on the formulated algorithm. The tables about minimum ratio of reinforcement to effective tensile region are showed for direct calculation of reinforcement which satisfy the requirement of crack width.

关 键 词：裂缝宽度验算 最小配筋率 计算程序
