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 [...]
In order to simplify the procedure for determining earthquake loads and effects in regions of low seismicity, a simplified static procedure has been introduced in National Building Code of Canada 2015. In this article, the force magnitude of a building in terms of the base shear, as determined in accordance with this simplified procedure, is compared [...]
ASTM F1554 covers three grades of anchor rods: Grade 36 (248 MPa), Grade 55 (380 MPa) and Grade 105 (724 MPa). The vast majority of anchor rods (as defined in CSA S16-14) are used to position, level and secure base plates for concentrically loaded gravity columns. Note: The expression “anchor rod” has replaced “anchor bolt” in [...]
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 [...]
A325 and A490 bolts are household names. What are F1852 and F2280? ASTM A325 AND A490 BOLTS are the high-strength bolts used for structural applications in North America. Their twist-off type counterparts are F1852 and F2280, respectively (Figure 1). ASTM standards A325M and A490M cover the metric versions (although metric bolts are rare). Generally, bolt [...]
