Design and Seismic performance of Ductile Steel CBFs in Canada

Steel Concentrically Braced Frames (CBFs) are widely used seismic-resistant systems in Canada and Europe. Despite their popularity, previous experimental and numerical investigations have revealed significant shortcomings, highlighting opportunities to refine the current seismic design provisions in both regions. The aim of this project is first to evaluate the seismic performance of moderately ductile steel CBFs designed to the Canadian standard, and then to assess the feasibility of braced frame designed with higher ductility capacities. Based on the outcomes, this project seeks to propose new design rules to improve the behaviour of these systems under seismic loads in both Canada and Europe. The improved seismic design rules are expected to reduce structural damage, economic losses, and risks to human life during major earthquakes. In addition, the proposed guidelines will enable the construction industry to achieve safer, more cost-effective, and optimized structural solutions. Moreover, the dataset and knowledge generated through this research will constitute a valuable resource for future investigations, advancing the state of the art in earthquake engineering and fostering the development of next-generation seismic design standards for steel CBFs.
