Connections are often the most overlooked part of structural design. We as structural engineers are educated in school of the many ways to analyze structural systems and to design beams and columns. But for many reasons, little time is spent on actual connection design. Perhaps in graduate school we have the chance to take an advance course on connection design, but often we are not truly exposed to the subtleties and complexities of steel connections until we are on the job, where, too often, we learn the biases and bad habits of our mentors.
In addition, most engineers in the US and Canada delegate the responsibility of connection design to the project’s fabricator. While this can be a good way to get cost effective connections, the Engineer of Record (EOR) often provides member designs that make it challenging for the fabricator’s engineer to get the connections to work for the loads given without reinforcing the members or choosing a costly connection type. This is especially true for connections that involve Hollow Structural Sections (HSS).
HSS connections have often been a source of additional mystery for even the most experienced engineers. For many years, there were not many resources here in the US that we as engineers could turn to for guidance on HSS connections. In the mid to late 1990’s, this started to change and over the past 20 years many excellent resources have evolved, especially with the inclusion of Chapter K in AISC 360.
This 1 hour presentation attempts to de-mystify HSS connections. While this is not a “how-to” guide, the presentation will highlight areas of HSS connection design that are often overlooked or misunderstood. Connection types that are addressed include tension, bracing, shear, moment and truss connections. Attendees will gain an appreciation of the similarities and the subtle differences between HSS connections and other types of connections.
Also addressed will be the effect certain design decisions have on fabrication and the cost of connections.
Speaker Bio: Brad Fletcher, S.E., is the senior sales engineer at Atlas Tube. In this role, Brad leverages his 28 years of experience in engineering design and the steel industry to provide technical expertise on the use of steel hollow structural sections (HSS) to design engineers and architects.
A registered structural engineer in the state of Illinois, Brad has held senior positions at leading architecture and engineering firms, Skidmore, Owings & Merrill; Sargent & Lundy; and Halvorson and Partners. For the past fourteen years, Brad has focused his efforts on serving as a liaison between structural designers and the steel industry.
Brad holds a BSCE and MSCE from Purdue University. He is active in many industry groups, including AISC, CISC, CSA, STI and ASTM International.
