2006年9月20日发布的AISC标准《核设施安全相关钢结构规范》（ANSI/AISC N690-06）包括荷载和阻力系数设计以及设计的容许强度设计方法，是AISC 2005《钢结构建筑规范》的补充。本文件适用于核设施中安全相关钢结构和钢构件的设计，并取代ANSI/AISC N690L-03和ANSI/AISC N690-94（R2004）。它已获得AISC规范委员会的批准，并获得ANSI认证。

This AISC standard, Specification for Safety-Related Steel Structures for Nuclear Facilities (ANSI/AISC N690-06), dated September 20, 2006, includes both the load and resistance factor design and allowable strength design methods of design, and is a supplement to the AISC 2005 Specification for Structural Steel Buildings. The document applies to the design of safety-related steel structures and steel elements in nuclear facilities and replaces ANSI/AISC N690L-03 and ANSI/AISC N690-94 (R2004). It has been approved by the AISC Committee on Specifications and it is ANSI-accredited.
