To calculate the shear stress, τ and angular deflection, θ caused by a torsional moment generated by the application of forces acting at some distance from the centroid, the polar moment of inertia for the respective section, Ϳ is required. Figure 1: Typical Tubular Sections For a Hollow Circular Tube: For a Hollow Square [...]
Bonnie Pankratz, President, AXIS Inspection Group Ltd. NDT Methods The most important question you need to ask when approaching Inspection and testing, is what do you want to accomplish? How does the inspection and testing that is done affect my bottom line and what information do you need for the application? This article is intended only [...]
Beam load tables for rectangular HSS have been published in the Handbook of Steel Construction up to the 10th Edition, 2010. Due to lack of space, these design tables were omitted in the 11th Edition, 2016. They are now being re-introduced as part of the CISC Steel Design Series. Figure 1 Steel Design Series SDS-7 [...]
The First Edition of " Single-Storey Building Design " is now available. This new 124-page publication is the 8th entry in CISC's Design Modules lineup. Design Module 8 (DM 8), Single-Storey Building Design, reviews the major design parameters and techniques used to produce a functional and efficient design of a storage/light industrial building enclosure using structural [...]

The Third Edition of "Moment Connections for Seismic Applications" is now available. It has been adopted, by reference, by CSA Standard S16:19 as an alternative to physical testing for the design of seismic moment connections. This new 56-page publication is also the 7th entry in CISC's Design Modules lineup. The First Edition of this CISC publication [...]

Seismic forces in a building structure must be transmitted from the roof and floor diaphragms to the vertical seismic force-resting system (and the foundations). In a steel-framed structure, they are typically transmitted via horizontal members, such as beams, joists and trusses, serving as collectors. Thus, the forces are typically transferred in shear between the sheet [...]
