不同规范下钢筋砼结构裂缝的计算与控制分析

以我国规范GB 50010—2002设计好的梁为基础，通过换算公式把个别已知的参数值转化为美国规范ACI3I8-89和欧洲规范Eurocode2 (EN 1992-1-1:2004)中相应的取值，再对这三种规范下钢筋混凝土结构的最大裂缝宽度的计算与控制进行比较分析。结果表明，我国规范的最大裂缝宽度计算值比美国规范、欧洲规范的要大，但在相似的工作环境下，我国规范对最大裂缝宽度的控制却相对较严。

Analysis of Calculation and Control for the Crack of Reinforced Concrete Structure Based on Different Code

Based on the beam have been designed by the code for design of concrete structures in China, the value of some parameters were converted into the corresponding value which are from the code in America and Europe by the conversion formula, and then the calculation and control of the maximum crack width of reinforced concrete structure come from these three code were compared and analyzed . The results show that the value of the maximum crack width obtained from the code in China is larger than American and European, but under the similar work environment, the control of the maximum crack width with the code in China is relatively stricter.
