ASTM A1085/A1085M, Standard Specification for Cold-Formed Welded Carbon Steel Hollow Structural Sections (HSS), was introduced in 2013 and was listed in CSA S16 Clause 5.1.3 for the first time in the 2014 edition. Figure 1 Hollow Structural Sections Wall thickness and mass tolerances for A1085 products are essentially the same as those specified for HSS [...]
Welded connections in structural applications are normally designed with matching electrodes, as listed in Table 4 of CSA Standard S16 for steels produced to CSA G40.21, "Structural Quality Steel". Starting with the 2014 edition, the S16 Standard now permits the use of non-matching electrodes with reference to CSA W59, "Welded Steel Construction - Metal Arc Welding", [...]
Eccentrically Loaded Weld Groups The second module in CISC's Design Modules lineup, "Eccentrically Loaded Weld Groups" is now available. The first module on "Eccentrically Loaded Bolt Groups" was the subject of a previous blog post: https://www.cisc-icca.ca/cisc-steel-design-modules-module-1-eccentrically-loaded-bolt-groups/ Design Module No. 2 covers traditional methods for determining the resistance of fillet weld groups in connections of various configurations [...]
Nova Scotia Government Expresses Commitment to Introduce Prompt Payment Legislation for 2019 Spring Session
With the ongoing involvement from the CISC to ensure prompt payment legislation across Canada, Premier Stephen McNeil commits to introducing prompt payment for the 2019 Spring session.
American Institute of Steel Construction (AISC) Launches Petitions to Impose Anti-Dumping and Countervailing Duties on Fabricated Structural Steel
The American Institute of Steel Construction (AISC) launches a trade action against China, Mexico and Canada on certain fabricated structural steel products. The CISC is confident that these investigations will prove that imports from Canada are fairly traded and cause no injury to U.S. producers.
Nova Scotia government expresses their enthusiasm and commitment to introduce prompt payment legislation for the 2019 Spring Session. The CISC Atlantic region will continue to play an active role in advocating for the needs of the construction industry so that legislation will be developed with Canadian tradespeople in mind.
Part 5 of the Steel Design Series (SDS-5) provides tables of properties and dimensions for the first series of Welded Wide-Flange (WWF) sections produced to metric dimensions, reprinted from the Handbook of Steel Construction, 2nd Edition, 1976. The tables are provided in both metric and imperial units, and they are intended mainly for designers involved in [...]
CISC is introducing the first module in a new lineup of upcoming Steel Design Modules. Module 1, "Eccentrically Loaded Bolt Groups", covers traditional methods for determining the resistance of bolt groups in connections of various configurations and subject to an eccentric point load applied either in-plane or out-of-plane. Bolt groups subject to an inclined point load [...]
The tables of Properties and Dimensions in Part 6 of the Handbook provide values of the depth (d), width (b) and wall thickness (t) of square and rectangular hollow structural sections (HSS). Values of the exterior and interior corner radii are not tabulated, however, mainly because these dimensions are not listed in CSA standard G40.20. Section [...]
