基于中美欧规范的500 kV变电构架计算分析

The calculation and analysis of the 500 kV substation framework based on codes from China,America and European

重点分析不同国家钢结构规范计算的差异,同时利用SAP2000空间结构分析软件对某海外500 k V变电站变电构架进行中美欧3个国家钢结构设计规范的验算,并详细分析不同国家规范计算结果产生差异的原因.结果表明,在钢材的利用上,美国规范最为精细,在荷载的取值上,欧洲规范最为保守.从设计的角度出发,美国规范和中国规范的用钢量接近,欧洲规范的用钢量最大.

We investigate the differences between design codes from different countries including codes from China,America and European,with software of SAP2000. Meanwhile,the causes of the differences are studied. The results show that the codes from America are the most refined in the use of steel and codes from European are the most conservative on the value of the load. From the view of the design,the codes from America,China are close to the amount of steel and code from European with the largest amount of steel.
