Graduated with a bachelor's degree in construction engineering from the École de technologie supérieure de Montréal (2006), and a master's degree in earthquake engineering at the École Polytechnique de Montréal (2012), Mr. St-Onge worked for several years for a steel fabricator as a frame and connection designer. In his career, he has designed several light commercial and industrial buildings. Today he works for Hydro-Québec as a seismic and steel structure specialist engineer. He supervises several construction and rehabilitation projects, including post-disaster building of substations, hydroelectric power stations, bridge of spillways, and crane structures. In recent years, he has designed a portion of the steel structure of the new Romaine 4 hydroelectric power station. Mr. St-Onge is known for his rigour, his technical knowledge and his dedication for the steel industry.

This session will overview the clause 27 of CSA S16-14 for the design of seismic connections. What information should the designer provides on his drawings for the detailer, for the design of connections under seismic loading. The intent of the session is to inform both designers and detailers about the design reality of both parties.

This session will overview the new provisions for ductile steel multi-tiered concentrically braced frames (MT-BF) in which braces meet at columns between diaphragms. First introduced in CSA S16-09 for Limit ductility (LD) only, now CSA S16-14 extended MT-BF for Type MD also. The presentation goal is to introduce Engineers to the design of ductile MT-BF, as per CSA S16-14.
