The current Canadian Highway Bridge Design Code CAN/CSA-S6-14 has incorporated performance-based design methodology for the design of highway bridges in Canada. Although force-based design can still be used in certain circumstances, performance-based design is now the preferred and often mandatory method of bridge design based on the Code requirements.

Engineers and Geoscientist British Columbia has recently published the Professional Practice Guidelines: Performance-Based Seismic Design of Bridges in BC. These guidelines are meant to provide a common level of expectation for various stake holders with respect to the level of effort, due diligence, and standard of practice to be followed. The document is intended to provide further clarity and guidance in applying the Code and the BC MoTI Supplement to the Code.

Description

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.

Course Outline

  • Overview of the guideline document
  • Professional registration, competence, quality assurance
  • Roles, responsibilities, and PBD process advantages for owners, designers, contractors, and clients

  • Performance and design considerations
  • Base-isolation and specialty product design
  • MoTI’s seismic program, earthquake emergency response, and seismic performance drawing
  • Case study review
  • Assurance statement

Speakers

Alireza Ahmadnia, PhD, P.Eng., PMP

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).

Upul Atukorala, P.Eng.

Principal, Senior Geotechnical Engineer, Golder Associates Ltd.

Dr. Upul Atukorala is a geotechnical engineer specializing in earthquake engineering, soil-structure interaction, and soil dynamics attached to Golder Associates’ Vancouver office. Over the past 30+ years, he has worked on and has served as a reviewer for a large number of projects involving seismic risk analysis, ground response analysis, soil-structure interaction analysis, liquefaction assessment of soils, analysis of liquefaction-induced ground displacements and evaluation of mitigative measures for liquefaction. Upul served as a member of the Seismic and Foundation technical subcommittees for S6-14 and the upcoming edition of the code.

Dane Doleman, P.Eng.

Structures Engineer, City of Vancouver

Dane Doleman is the City of Vancouver’s Structures Engineer tasked with managing the City’s seawall and bridge inventory. In addition to assessing the seismic risks and vulnerabilities of the City’s bridge inventory, recent focus has been placed on updating emergency response plans and developing tools to assist municipal staff and responding consulting engineers.

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.

Saqib Khan, P.Eng.

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.
