摘要
对ＪＧＪ１９－９２《冷拔钢丝预应力混凝土构件设计与施工规程》规定的构件抗裂检验系数容许值［ｒｃｒ］的计算公式进行了讨论。为避免混淆概念，改变计算公式表达形式。
This paper discusses the formulae of (4.7.4-2) and (4.7.4-3)in Code of Design and Concrete Menbers Prestressed with Cold -Drawn Wires (JGJ19-92),which are used to calcelate the permissible value for the check coefficient of the memeber crack resistance.The paper points out that the formulae of the code outht to be changed in expressing forms .in order to avoids the confusion in concept.The (4.7.4-3) formula should belinited in using the code.
