ASTM F3125/F3125M:2019钢结构用高强度螺栓连接副标准解读

ASTM F3125/F3125M:2019e2 Interpretation of the Standard for High-strength Bolt Connections for Steel Structures

ASTM美国材料试验协会于2015年首次发布ASTM F3125《钢结构用高强度螺栓连接副》,以替代ASTM A325/A325M、ASTM A490/A490M等4个高强度大六角头螺栓副和ASTM F1852/F2280二个高强度扭剪型螺栓标准。新标准的整合是为了保证相同用途的多个标准得到统一、合并,消除重复使用所有等级、产品型式等技术条件,确保该系列产品能满足工程的使用及维护,并与原标准保持一致。ASTM F16.02于2019年11月修订发布ASTM中F3125/F3125M:2019e2第四版标准。

ASTM American Society for Testing and Materials first published ASTM F3125 Standard Specification for High Strength Structural Bolts and Assemblies,Steel and Alloy Steel,Heat Treated,Inch Dimensions 120 ksi and 150 ksi Minimum Tensile Strength,and Metric Dimensions 830 MPa and 1040 MPa Minimum Tensile Strength in 2015 to replace four high-strength large hexagon head bolt pairs such as ASTM A325/A325M and ASTM A490/A490M and ASTM F1852/F2280.A high-strength torsion shear bolt standard.The integration of the new standard is to ensure that multiple standards with the same purpose are unified and merged,and to eliminate technical conditions such as repeated use levels and product types,and to ensure that the series of products can meet the use and maintenance of the project and be consistent with the original standard.ASTM F16.02 revised the fourth edition of ASTM F3125/F3125M:2019e2 in November 2019.
