［摘要］通过对中国、欧洲标准中混凝土结构的耐久性、材料及构造要求的对比研究，发现欧标中环境类别的划分更为细致。国标对混凝土最大水胶比、最大氯离子含量要求略小于欧标，而欧标要求的混凝土最低强度等级高于国标。给出了中、欧混凝土抗压和抗拉强度设计值在同等条件下的取值，中、欧标准抗压强度设计值相差不大，但欧标采用的抗拉强度设计值明显小于国标；中、欧标准中钢筋强度等级不同，目前国标钢筋强度等级仍低于欧标。中、欧标准中钢筋屈服强度取值不同，目前国标钢筋强度的水平仍明显低于欧标。欧标中最小保护层厚度、裂缝宽度限值要求大于国标要求，国标中受拉钢筋的锚固和搭接长度大于欧标，而国标中受压钢筋的锚固和搭接长度小于欧标，欧标中要求的伸缩缝间距小于国标，中、欧标准对钢筋混凝土受弯构件的挠度限值要求基本一致。

Abstract:Through the comparative study of durability, materials and structural requirements of concrete structures between Chinese and European standards, it is found that the classification of environmental categories in European standards is more detailed. The requirements of the Chinese standard for the maximum water binder ratio and the maximum chloride ion content of concrete are slightly less than those of the European standard, while the minimum strength grade of concrete required by the European standard is higher than that of the Chinese standard. The design values of compressive strength and tensile strength of concrete in Chinese and European standards were given under the same conditions. The design values of compressive strength in Chinese and European standards are similar, but the design values of tensile strength adopted in European standards are obviously smaller than those in Chinese standards. The strength grades of steel bars in Chinese and European standards are different, and the strength grades of steel bars in Chinese standards are still lower than those in European standards. The yield strength of steel bars in Chinese and European standards is different, and the strength level of steel bars in Chinese standards is still significantly lower than that in European standards. In the European standard, the minimum thickness of protective layer and crack width limit are required to be greater than the requirements of the Chinese standard, the anchorage and lap length of tensile steel bars in the Chinese standard are greater than the requirements of the European standard, while the anchorage and lap length of compression steel bars in the Chinese standard are less than the European standard, and the expansion joint spacing required in the European standard is less than the Chinese standard. The requirements of the Chinese and European standards for the deflection limit of reinforced concrete flexural members are basically the same.
