【摘要】 为进一步深入了解和掌握外国规范，针对火电厂变电架构设计方法，从架构设计方法、荷载取值、荷载组合、构件设计和变形限值等方面，对比分析了我国《变电站建筑结构设计技术规程》(统称国标)与外国标准《Substation Structure Design Guide》(统称外标)的异同；通过比较发现，中外规范相关规定相近，只是参数取值略有差异。通过实际工程算例比较可知，与外标计算结果相比，国标的计算结果偏于经济，对其他海外工程具有一定的指导意义。更多还原

【Abstract】 To further understand and master international codes, in terms of the design method of the switchyard structure, the similarities and differences between Chinese codes Technical Code for the Design of Substation Buildings and Structures DL/T 5457-2012 and international codes Substation Structure Design Guide”ASCE are compared and analyzed, including design methods, load values, load combinations, component designs, deformation limits and so on. The comparative results indicate that the relevant provisions of the Chinese and international standards are similar, but the parameter values are slightly different.According to the actual engineering projects, compared with the calculation results of international standards, the calculation results of Chinese standards tend to be economical, and the results have a certain guiding significance for other overseas projects.更多还原
