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 [...]
Engineers are often faced with the challenge of determining the yield strength or tensile strength of structural steel members found in historical steel buildings. This becomes particularly important for rehabilitation and renovation works. The table below is an excerpt taken from Part Six of the CISC Handbook of Steel Construction. Note that the yield strength and [...]
The Canadian Institute of Steel Construction’s Solutions Centre is pleased to announce the launch of its new technical blog, Steel Knowledge. As engineering boundaries expand and steel design and fabrication evolve, engineers, architects and fabricators are sure to benefit from this vital source of information. This new blog aims to foster the development and sharing of [...]
