This seminar will provide an overview of the document with an in-depth discussion on the roles, responsibilities, and the performance-based design advantages and challenges for various parties. Limitations of the force-based design and basic concepts of performance-based design will be discussed along with seismic hazard assessment and soil-structure interaction analysis. An introduction to the BC Ministry of Transportation and Infrastructure’s seismic program will be provided along with the drawing format, expected to be prepared by the consultants, summarizing the anticipated post-earthquake bridge performance. Two case studies will be discussed to show key analysis and design requirements required for performance-based design of bridges. The key points of the Assurance Statement to be prepared by the Engineer of Record will also be discussed.

Senior Bridge Seismic Engineer, BC Ministry of Transportation and Infrastructure
Alireza is a Senior Bridge Seismic Engineer at the BC Ministry of Transportation and Infrastructure. He is responsible for leading and developing the bridge seismic design and retrofit standards, the bridge seismic retrofit program, new and improved structural earthquake analysis tools and methods, and the post-earthquake response plan for bridges. Alireza has extensive background in the earthquake engineering discipline in seismic design, analysis, assessment, and upgrading of structures. His work experience includes the design, analysis, and independent check of several signature cable-stayed, suspension, and truss bridges in high seismic zones such as work on the South Fraser Perimeter Road Project (BC,CA), Pattullo Bridge (BC, CA), Tappen Zee River Crossing (NY,USA), and Chacao Bridge (Chacao, Chile).

Sharlie continues to be involved in professional excellence through Engineers and Geoscientists of BC, having previously served on Council and many committees including the Continuing Professional Development Committee, and currently serving on the Professional Practice Review Committee, and co-authoring the latest Professional Guidelines for Bridge Performance-Based Seismic Design. Sharlie is a long-time member and current Vice-President of the Canadian Association of Earthquake Engineering.
Vice President, Transportation Structures, Associated Engineering
Don has 35 years of experience in bridge engineering and construction in Canada and internationally. He has specialized in bridge rehabilitation and retrofit, new bridge design, earthquake engineering and dynamic analysis, bridge instrumentation and monitoring, advanced seismic engineering and forensic engineering. His rehabilitation and retrofit experience includes major steel bridges including trussed arches, trusses, suspension and cable-stayed bridges. He has worked on bridge rehabilitations in BC, Ontario, and New Zealand. Don has also worked on the design and construction of many major bridges, including the several river and harbor crossings in British Columbia. He has published numerous conference papers and journal papers, has contributed as a presenter to seismic design seminars across Canada, was a co-author of the Engineers and Geoscientists BC bridge design guidelines for engineers, and lead the development of the BC Supplement to S6-14 (2016), the Engineers and Geoscientists BC guidelines (2018) on performance-based seismic design.
Don is the Chairman of the seismic sub-committee of the national bridge code, the Canadian Highway Bridge Design Code, having been a technical member since 2002. He was a technical member of the AREMA (railway) bridge design code (Chapter 9, seismic) between 2002 and 2015. He has a master’s degree in applied science from McMaster University, and is registered to practice engineering in a number of provinces.
Technical Manager - Bridges, McElhanney Consulting Services Ltd.
Saqib Khan is a structural engineer with 18 years of work experience. He has worked with both the private and public sectors and has gained extensive experience in the inspection and assessment of bridges, as well as analysis and design. Saqib has extensive experience on seismic-resistant design, live load assessments, and assessment of fatigue and other bridge deficiencies. He currently acts as the Technical Manager for the Bridge Division at McElhanney Consulting Services Limited.
Saqib has been involved in active research and supervising master’s students at University of British Columbia (UBC) through university-industry collaboration initiatives. He has supervised and directed recent research on the implementation and comparison of force-based and performance-based design of bridges per the Canadian Highway Bridge Design Code, CAN/CSA-S6-14. He’s recently been involved with research on the performance of eccentrically-braced steel frames as bridge substructures. Saqib has authored and co-authored several papers and was the lead author for the recently published Professional Practice Guidelines titled Performance-Based Seismic Design of Bridges in BC published by Engineers and Geoscientists British Columbia. These guidelines outline the appropriate standard of practice to be followed when carrying out performance-based design of bridges in BC.
