ANSI/AISC 370-21《结构不锈钢建筑规范》PDF下载
这是美国钢结构协会(AISC)首次专门针对“结构级不锈钢”发布的国家标准,与360系列碳钢规范并行,适用于304/304L、316/316L、2205双相等奥氏体、铁素体及双相不锈钢的梁、柱、桁架、节点和板件设计。核心亮点包括:

1. 材料性能单独成表:给出不锈钢各牌号的**规定屈服强度Fy、抗拉强度Fu、应变硬化指数n、热膨胀系数及低温冲击韧性**,解决以往借用碳钢指标导致的安全裕度不明问题。
2. 稳定性设计“双路径”:保留有效长度法,同时新增**直接分析法(DM)**,并提供不锈钢**τb刚度折减系数表**,可一次性考虑开口截面、焊接残余应力及非线性应力-应变关系。
3. 连接专章:针对不锈钢**低导热、高电阻**特点,规定**激光/激光-电弧复合焊**的工艺窗口、焊材匹配及层间温度限值;螺栓连接给出**耐腐蚀垫圈、斜面垫片**及**最大孔径、最小边距**全套参数,可直接写入采购清单。
4. 疲劳与断裂:附录3提供**S-N曲线热点应力法**与**焊缝细节类别**,与AISC 360-22附录3互补,适用于桥梁、屋面、海洋平台等循环荷载场景。
5. 耐火设计框架:附录4给出**临界温度折减系数**与**高温强度保持率**,与ASCE 29-22、NFPA 5000性能化防火对接,为超高层不锈钢外框柱-核心筒混合结构提供量化验算路径。
