QUESTION 1: Within the CFS industry, there appear to be varying definitions of nominal thickness for coldformed steel gauge. Is there a standard for cold-formed steel thickness and tolerances? ANSWER: There are various definitions of thicknesses when it comes to cold-formed steel design such as minimum base steel thickness and design thickness, which, along with tolerances, [...]

Braced Frames for Low to Moderate Seismicity, published by the CISC, illustrates the design of seismic force-resisting systems (SFRS) and brace-to-gusset connections for concentrically braced frames in areas of low to moderate seismicity (See Figure 1). The design notes refer extensively to the National Building Code of Canada 2015 (NBC 2015) and to CSA S16-14, Design [...]
The updated, second edition of Industrial Steel Structures, by R.A. MacCrimmon and J. Richard, was published earlier this year. It can be obtained from the CISC Steel Store (https://steelstore.cisc-icca.ca/). See Figure 1. This CISC publication was expanded from 148 pages (in the first edition) to 201 and illustrates the design of a typical mill building carrying [...]
NOW AVAILABLE The fourth edition of Crane-Supporting Steel Structures: Design Guide, by R.A. MacCrimmon, is now available at the CISC Steel Store (https://steelstore.cisc-icca.ca/). Past editions of this CISC publication have filled a long-standing need for technical information for the design and construction of crane-supporting steel structures according to Canadian codes and standards written in limit states [...]
Two new entries in CISC's Steel Design Series were published in August 2021: Lightweight Steel Framing Solutions and Steel Paints for Slip-Critical Connections. Both are available as free downloads at the Steel Store. Lightweight Steel Framing Solutions (Figure 1) focuses mainly on floor and roof members, and the following framing systems are considered: ▪ Open-web steel joists (OWSJs) ▪ Castellated and cellular beams [...]

The new 12th edition of the Handbook of Steel Construction based on CSA S16:19, Design of steel structure, is now available. Published by the CISC since 1967, the Handbook of Steel Construction is the standard reference for the design and detailing of structural steel in Canada. The 12th Edition has been updated to reflect changes to [...]
Question 1: How to calculate the shear stresses in straight plug welds connecting two plates. Question 2: How to calculate the shear stresses in bevelled plug welds connecting two plates. Question 3: How to calculate the shear stresses in straight slot welds connecting two plates. Question 4: How to calculate the shear stresses [...]
CISC has published its latest Design Module: Steel-Framed Commercial Building Design. This publication illustrates the design of a six-storey commercial building, including common structural steel components used in floor and roof framing such as composite girders and open-web steel joists. The module is intended to be used in conjunction with CSA Standard S16-14, Design of steel [...]
