Structural steel detailing on Minnesota projects is checked against both the state building code and the national standards it incorporates by reference.
The 2020 Minnesota State Building Code, effective March 31, 2020, adopts the 2018 IBC as the Minnesota Building Code under Minnesota Rules Chapter 1305. Chapter 22 of the IBC governs steel construction and incorporates AISC 360 by reference for structural steel design, along with ASCE 7 for minimum design loads - snow, wind, and seismic - that directly affect connection sizing and framing layout on Minnesota projects. Minnesota's six-year code adoption cycle keeps this base stable longer than the ICC's standard three-year cycle; the next update is expected around 2026–2027, anticipated to move to the 2021 IBC family.
Welded connections are detailed to AWS D1.1, the structural welding code referenced across virtually every steel fabrication shop's quality program, and high-strength bolted connections follow the RCSC Specification. We confirm which code and standard edition applies to your specific jurisdiction and submittal date before detailing begins, since Minnesota's state code is only enforceable where a municipality has adopted it by local ordinance.
