The issues related to the AWS D1.8 Seismic Welding Supplement are discussed. The first D1.8 Seismic Welding Supplement, approved by the AWS D1 Committeen in 2005, is expected to be used together with the AISC Seismic Provisions. D1.8 focuses on connection details, materials, workmanship, and inspection issues, while most of the design-related issues are covered in AISC standards. These topics are covered in seven sections namely general requirements, reference documents, definitions, welded connection details, welder qualification and fabrication. It is necessary, under D1.8 welding procedure specifications (WPSs), to list the filler metal manufacturer as well as the filler metal trade name in addition to the AWS classification. It is also expected that the AWS D1.8, when specified and properly implemented, and when used with the AISC Seismic Privisions, will significantly improve the performance of steel buildings.
