| 摘 要： | 针对中欧混凝土结构设计规范的异同点,在混凝土强度等级、保护层厚度、环境暴露等级等方面进行对比论述,并分析欧洲规范的承载能力计算、裂缝开展宽度计算原理。以实际项目为例,对受弯构件的承载能力、配筋和裂缝宽度等进行定性分析,得出同等条件下中国规范较欧洲规范的裂缝计算值更大但裂缝控制更为严格等结论,为海外项目结构设计提供参考。

| Abstract: | Aiming at the similarities and differences between Chinese code and Eurocode of concrete structure design,we contrast and discuss the strength grade of concrete,the thickness of concrete cover and the concrete exposure levels,and analyze the carrying capacity of the target of reinforcement and the crack width calculation principle.Based on an actual project as an example,we analyze qualitatively carrying capacity,reinforcing bars and the crack width of flexural member.The results show that in the same situation the crack calculated by Chinese code is larger than that by Eurocode,also the crack controlling by Chinese code is stricter.The results can provide reference to the overseas project structure design. |
