The Research Council on Structural Connections (RCSC) Specification for Structural Joints Using High-Strength Bolts provides state-of-the-art criteria for design and installation of ASTM high-strength bolts and assemblies. These recommendations become mandatory if and when the local code adopts them. In Canada, structural design and inspection of bolted joints and installation of high-strength bolts should comply with [...]
One of the most prominent features in the Handbook of Steel Construction, 11th edition, is the addition of availability data for wide-flange or W-shape sections. In Parts 4, 5 and 6, W-shapes that are commonly used and readily available are highlighted by the colour yellow, as shown on the accompanying figure. The design tables in which [...]
The CISC has developed 6 verified & registered industry average Environmental Product Declarations (EPDs) for structural steel that are available from authorized CISC fabricator members. Click here for more information on CISC Structural Steel EPDs
Reputable global EPCs (Engineering, Procurement, Construction ) operating in Canada know something that you may not. They are mandating that all steel used on their projects be produced/rolled in North America. They claim to be doing this because of trust (or the lack thereof) of global material supply. In a global market place that seems pretty [...]

Steel Section Dimensions provides the main section dimensions (d, b, t, w) of structural steel shapes listed in the CISC Handbook of Steel Construction, 11th Edition. Dimensions can be displayed in metric or imperial units. The available steel shapes include: W, HP, M, S, C, MC, L (equal and unequal-leg), HSS (Square, Rectangular and Round) produced [...]
Designers must consider material availability when specifying section sizes, particularly for the heavier sizes in a nominal size range, and for small quantities of the less commonly used sizes. As regional availability of steel products varies, information on the availability of particular sizes can be obtained from either local steel fabricators, producers, and service centres. The [...]
The minimum size of a fillet weld as measured should comply with Table 4.4 of CSA W59-13, unless a larger size is required to provide the calculated weld resistance. The long-standing code provision for minimum fillet size aims to reduce the cooling rate. The presence of hydrogen and fast cooling are major contributing factors for cold [...]
Knife edge angle connection, commonly known as knife connection, is a very common type of beam shear connection. It features a pair of angles that are typically welded to the column in the shop and bolted to the beam web in the field (Figure 1). While knife connection serves as a popular beam shear connection, its [...]
In accordance with the National Building Code, steel building systems shall be manufactured by companies certified to CSA A660 “Certification of Manufacturers of Steel Building Systems.” A steel building system (SBS) features steel for the structural components plus related accessories engineered and designed as a total building system, commonly referred to as “pre-engineered buildings” for which [...]
