CSA S16:19 PDF Download

CSA S16:19 is the ninth edition of the standard and supersedes previous editions published over the years. The standard provides rules and requirements for the design, fabrication, and erection of steel structures using a limit states design approach. It covers a wide range of steel structures, including those composed of structural steel components acting compositely with concrete.

The major changes in this edition include updates to terminology, references to high-strength bolts using ASTM standards, improved clarity in distinguishing between specified and service loads, inclusion of inelastic analysis as a defined analytical method, additional guidance for stability analysis and design, expansion of width-to-thickness class criteria for certain sections, restructured provisions for designing compression members, provisions for designing single angles as beams, improved wording for lateral-torsional buckling of beams, and new provisions for designing built-in cantilevers and using HSS members as beam-columns, among others.

The standard also addresses seismic design for moderately-ductile plate walls and truss moment-resisting frames, introduces seismic categories for detailing requirements, provides guidance on multi-tiered bracing and seismic foundation rotations, and includes provisions for third-party inspection. It also covers control of brittle fracture, design for fire conditions, and storage racks.

CSA S16:19 is intended to be used in conjunction with the 2020 edition of the National Building Code of Canada (NBC) for load factors, load combinations, and other loading provisions. The standard has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada.
