摘要
主要就现行中国钢结构设计规范与欧洲钢结构设计规范中受压构件的设计规定进行比较。从轴压构件的设计方法、压弯构件的设计方法与局部稳定的构造要求等方面对两套规范进行对比分析。研究发现,我国轴压构件设计的安全性更高,压弯构件设计的安全性较低,在局部稳定的构造要求上还不够细致。建议我国提高压弯构件设计的安全性,并且按照截面类型、板件应力分布等方面细化局部稳定的构造要求。
A comparison of stability bearing capacity of compression member is carefully studied between Chinese code and Eurocode 3, including design methods for axial compression members, axial-bending members and detailed structural requirements to avoid local buckling. The results show that the design method for axial compression element is stricter in Chinese code than Eurocode 3. The design method for axial bending element is stricter in Eurocode 3 than Chinese code. Besides, the detailed requirements in EC 3 are more particular. It is recommended to improve safety of design of axial-bending elements in Chinese code and refine the structural requirements in terms of section classification and stress distribution of plate element.
