Comparison of Design Verification Methods for Steel Members Between Chinese and American Codes
-
摘要: 随着越来越多的国内单位承接国外工程项目,工程人员急需熟悉国外规范。AISC 360-10是美国钢结构设计规范,在钢结构计算方法、稳定验算理论、结构构造要求等方面均与我国的GB 50017—2017《钢结构设计标准》存在明显的差别。针对钢结构构件验算方法,对AISC 360-10和GB 50017—2017进行了系统比较,分别从钢构件抗压、抗弯和抗剪承载力方面分析了AISC 360-10和GB 50017—2017所提供的构件验算方法的区别,并通过典型构件案例,定量分析了两本规范计算得到的结果差异。研究结果可为相关国外钢结构工程的初步判断提供依据,尤其对于采用国内规范进行初步设计的情况,可参考研究结论对最终采用美国规范的设计结果进行初步判断。Abstract: In recent years, as Chinese companies have undertaken more overseas projects, a deep understanding of foreign construction and design codes has become increasingly important. The American steel structure design code, AISC 360-10, is one of the most advanced specifications in this field. There are significant differences between AISC 360-10 and the Chinese steel structure design code, GB 50017-2017, such as analytical methods, stability design theory, and detailing requirements. A systematic comparison was conducted on the analysis about the member verification methods between AISC 360-10 and GB 50017-2017 for steel structures. Typical members under axial compression, bending, and shear were checked respectively according to AISC 360-10 and GB 50017-2017. Furthermore, typical member examples were employed to quantitatively compare the results obtained from the two codes. The conclusions drawn from this study can serve as a reference for the preliminary design of overseas projects and are particularly useful for making preliminary assessments of overseas projects that were initially designed according to GB 50017-2017.
