It was a project Cast Connex was involved in about a year ago that really crystallized the need for standardized tapered ends for hollow structural sections (HSS) for use in architecturally exposed structural steel (AESS). The project is the Woods H*** Oceanographic Institution'...
Read moreRigid moment-resisting beam-to-HSS column connections There are a number of public domain connection solutions for moment-resisting frames under high seismic loading available as prequalified designs in AISC 358, however none of these pertain directly to hollow structural s...
Read moreAs the usage and popularity of hollow structural sections (HSS) continue to grow, it’s important to provide opportunities for engineers to...
Read moreTruss connections are connections at the panel points of a planar truss, and are designed as tension/compression connections. In this video I discuss the specifics of trusses with HSS, including joint types, fabrication costs, failure modes, design approaches, welding, and more. As a key takeaway, some of the top things to think about when desig...
Read moreAs we mentioned in our last installment of the Designing with HSS video series, HSS connections have some seriously unique challenges. Moment connections are used to develop continuity and rigidity between a beam and a c...
Read moreThe Designing with HSS video series is back. In the latest video, I discuss the various types of connections and the unique challenges involved when designing with hollow structural sections. Check it out. The following are the top three key takeaways for designing with HSS connections: The...
Read moreThe design of HSS members took a huge step forward with Dr. Jeffrey Packer's manuals and programs and the inclusion of this information in Chapter K of the AISC Specification. Previously, it was believed that HSS connections were so complex they would increase the...
