摘要
本文采用钢筋混凝土计算力学的方法 ,推导了采用粘结极限强度计算的最大裂缝宽度计算公式。并与《混凝土结构设计规范》(GBJ10 89)的裂缝公式进行比较 ,结果表明 :《规范》中对低配筋率的钢筋混凝土构件最大裂缝宽度计算公式是有待探讨的。
This paper calculates the crack width of reinforced concrete members by computational mechanics of reinforced concrete.And a formula for the maximum width with limit strength of bonding is suggested.As compared with the formula of crack width in “The design Code of Concrete Structures” (GBJ10\|89),analysis shows that the availability of the formula of the maximum width for low feinforcement radio members is doubtable.
