Steel Design Series – Welded Shapes

Part 4 of the CISC Steel Design Series (SDS-4), "Welded Shapes - Properties and Dimensions" has been published. Tables of Welded Wide-Flange (WWF) and Welded Reduced-Flange (WRF) shapes are reprinted from the Handbook of Steel Construction, 10th Edition. They are intended mainly for designers involved in renovation projects. Essar Steel Algoma Inc. had been the prime [...]

Class 4 Compression Members in the Handbook

Part 4 in the Handbook of Steel Construction contains tables of factored axial compressive resistances. For a small number of compression members, the width-to-thickness ratio of the flanges and/or web exceeds the limits given in CSA S16-14 Table 1. The compressive resistance of members subject to elastic local buckling (Class 4 sections) may be calculated using [...]

Technical Resources for Obsolete Steel Sections

When renovating older buildings, designers have often turned to the CISC Solutions Centre for information on obsolete steel sections listed in past editions of the Handbook. This information can be found on the CISC Technical Resources webpage at the link below: https://www.cisc-icca.ca/technical-resources/ Properties and dimensions listed in the Handbook of Steel Construction, 1st Edition 1967, are [...]

Member Tolerances

Tolerances on hot-rolled steel members include permissible variations in the mass, area, length, cross-sectional dimensions (depth and flange width), straightness (camber and sweep), and other geometric properties. Manufacturing tolerances are given in CSA Standard G40.20, which in turn refers to ASTM A6/A6M for structural shapes. A summary of the basic tolerances can be found on pages [...]

Detailing Dimensions in the CISC Handbook

One of the more innocuous changes in the 11th edition of the Handbook of Steel Construction is the updating of detailing dimensions in Part 6. As shown on the figure below, k and k1 depend not only on the flange and web thicknesses, respectively, but also on the radius of the round flange-to-web fillet, r. Since [...]

Galvanized Bolts on Weathering Steel

The question of galvanic corrosion can arise when dissimilar metals, or different methods of corrosion protection (such as galvanized bolts and weathering steel), come into contact. One example application involves galvanized bolts and angles supporting conduits on a bridge made of 350A (atmospheric corrosion-resistant, weldable) steel or its notch-tough counterpart, 350AT steel. Can galvanized high-strength ASTM [...]
