DESCRIPTION:This webinar is a hybrid presentation. Online attendees should pre-register to receive the Zoom Webinar Link. In-person attendees are welcome to attend at UBC CEME 1204 without registration. \n\n\n\nVenue:   \nOnline attendees: Zoom Webinar\nIn-person attendees: UBC CEME 1204 – 6250 Applied Science Lane\, Vancouver BC.  V6T 1Z4\n\n\nCost:   \nOnline attendees: Free for members\, $30 for guests and non-members\nIn-person attendees: Free\n\n\nSpeaker:   \nAndrew Whittaker\, Ph.D.\, P.E.\, S.E.\nSUNY Distinguished Professor\, University at Buffalo\n\n\n\nAbstract \nRisk-informed pathways are being developed for the design and licensing of next generation nuclear facilities. This presentation will address one such pathway to implement seismic base isolation\, which involves the development of a) isolation-system-specific seismic displacement demand curves from seismic hazard curves\, and b) fragility functions for seismic isolation systems. Risk calculations result in a displacement\, D50\, that forms the basis for the prototype testing of isolators and dampers. Specific topics addressed in the presentation include the derivation of the displacement demand curves and isolation-system fragility functions\, and calculations of risk.

SUMMARY:Use of NRC’s Newly Released Seismic Evaluation and Upgrading Guidelines
DESCRIPTION:Workshop Overview\nEarthquakes are among the most destructive natural disasters\, capable of causing severe casualties and significant economic losses. For building owners\, assessing and mitigating seismic risks in existing buildings poses both technical and economic challenges. In Canada\, there has long been a need for nationwide technical guidelines for seismic evaluation and upgrading. The National Research Council Canada (NRC) first addressed this in the 1990s by publishing Guidelines for Seismic Evaluation of Existing Buildings and Guideline for Seismic Upgrading od Building Structures. However\, these documents were never updated and have since become outdated. \nCurrently\, the National Building Code of Canada (NBC) Commentary L recommends ASCE 41 Seismic Evaluation and Retrofit of Existing Buildings as a reference for seismic evaluation and upgrading. While comprehensive\, ASCE 41 is based on American design and construction practices\, and its direct applicability to Canada requires careful consideration. \nRecognizing this gap\, the Seismic Resilience Team at NRC’s Construction Research Centre has spent the past seven years developing updated\, Canadian‑specific technical guidelines—the newly released Level 3 – Seismic Evaluation Guidelines (SEG) and Seismic Upgrading Guidelines (SUG) for existing buildings in Canada. \nDesigned to help professionals apply these new guidelines for effective implementation\, and to improve safety and resilience of existing buildings\, a series of webinars and training workshops are being delivered by the NRC in partnership with CAEES. \nBuilding on the success of previous webinar series\, this two‑day in-person training workshop offers 10 hours of advanced training sessions designed to deepen your understanding and practical skills: \n\nHands-on exercise applying the Tier 1 Quick Evaluation Procedure of the Level 3 – SEG to a hypothetical building located in Vancouver\, British Columbia.\nOverview of Tier 3 Non-linear Static Analysis Procedure (NSAP) in the Level 3 – SEG.\nStep‑by‑step demonstration of Tier 3 NSAP for a simple three‑storey steel moment‑resisting frame.\n\n\nWorkshop Program\n\n\n\n\nDay 1: Monday\, February 23rd\, 2026 \n\n\n\n8:30-9:00  \nRegistration\n\n\n9:00:10:15\nLecture 1 \nOverview of Level 3 – SEG\nReza Fathi-Fazl\n\n\n10:15-10:45\nCoffee Break\n\n\n10:45-12:00\nLecture 2\nOverview of SUG\nFarrokh Fazileh\n\n\n12:00-13:00\nLunch Break\n\n\n13:00-14:00\nLecture 3\nApplication of Tier 1 Quick Evaluation Procedure\nZhen Cai\n\n\n14:00-14:30\nCoffee Break\n\n\n14:30-15:30\nLecture 4\nApplication of Tier 2 Deficiency-Based Evaluation & Deficiency-Based Upgrading Procedures\nFarrokh Fazileh\n\n\n15:30-16:00\nQ&A and Discussion\nReza Fathi-Fazl\, Farrokh Fazileh and Zhen Cai\n\n\n\nDay 2: Tuesday\, February 24th\, 2026 \n\n\n\n9:00-10:00\nLecture 5\nOverview of Tier 3 Detailed Evaluation Procedure\nReza Fathi-Fazl\n\n\n10:00-10:30\nCoffee Break\n\n\n10:30-12:00\nLecture 6\nApplication of Tier 3 Non-linear Static Analysis Procedure (NSAP)\nFarrokh Fazileh\n\n\n12:00-13:00\nLunch Break\n\n\n13:00-15:00\nLecture 7\nHands-on Exercice on Tier 1 Quick Evaluation Procedure\nZhen Cai\, Farrokh Fazileh and Reza Fathi-Fazl\n\n\n15:00-15:30\nCoffee Break\n\n\n15:30-16:00\nLecture 8\nDiscussion of Tier 1 Quick Evaluation Results\nZhen Cai\, Farrokh Fazileh and Reza Fathi-Fazl\n\n\n\n  \nPresenter’s Biography\n\n\n\n\n\nReza Fathi-Fazl\, Ph.D.\, P.Eng.\nSenior Research Officer\nNRC\n(Gholam-Reza.Fathi-Fazl@nrc-cnrc.gc.ca) \n\nDr. Reza Fathi-Fazl\, P.Eng. is a Senior Research Officer and the Director of R&D for the Sustainable Resilient Infrastructure and Communities (SRIC) unit at the National Research Council Canada (NRC).

SUMMARY:John Hart Dam Seismic Upgrade: A Robust Seepage Barrier for Cascadia Megathrust Resilience
DESCRIPTION:Abstract\nThe John Hart Dam\, constructed in the late 1940s on Vancouver Island\, required upgrades to address seismic vulnerabilities and ensure resilience against a potential magnitude M9 mega earthquake originating from the nearby Cascadia Subduction Zone. The Middle Earthfill Dam (MED)\, one of three earthfill structures at the site\, was determined to be at risk of flow slide failure or significant displacements due to liquefiable and strain-softening foundation soils. Many conventional ground improvement techniques were unsuitable due to environmental sensitivities\, constructability challenges\, and dam safety concerns\, especially given the need to avoid reservoir drawdown and cofferdam installation. To overcome these limitations\, a range of solutions—from straightforward to moderately complex—were implemented to rehabilitate the various structures. These included an upstream buttress berm with dredging and replacement under full reservoir conditions\, unloading by excavation\, and a downstream toe berm reinforced with steel pinning piles. A key element was the construction of a new Plastic Concrete Cutoff Wall (PCCW) to replace the vulnerable slurry trench cutoff wall\, providing a robust and seismically resilient seepage barrier. The PCCW was embedded into bedrock or silt and constructed with a suitable mix to ensure durability and reliability. The presentation will outline the overall upgrade strategy and focus on the PCCW’s design and construction\, highlighting key challenges and performance verification. The seismic upgrade of the dam is ongoing\, with the PCCW completed in early 2024.

SUMMARY:The Evolution of Performance-based Seismic Design of Bridges in Canada
DESCRIPTION:Abstract\nThe seismic design of bridges in British Columbia has followed international evolving practices since the early 1980’s. Circa 1990\, the Province of BC embarked on a bridge retrofit program including the Vancouver region’s nine major river and harbour crossings. These projects drew on local engineering skills plus technical expertise from internationally recognized experts in structural and geotechnical engineering. The seismic design of new bridges in BC also evolved with the development of modern seismic design tools and methods\, and from their application to these technically challenging retrofit projects. The 1990’s retrofit phase in BC targeted collapse-prevention upgrades to major bridges built in the 1950’s to 1970’s. This “Safety” retrofit was phase 1 of a planned two-phase retrofit program\, with ‘functional’ seismic upgrades to follow. In recent years\, the higher-level “functional” retrofit objective came back into focus. Engineers\, planners and governments learned lessons from recent earthquakes and of the importance of designing for a rapid return to service for our transportation networks after large earthquakes. Hence the Ministry is currently reviewing the implications of functional-level upgrade needs\, costs and benefits to inform the design and construction of additional retrofit works. During this time\, performance-based seismic design philosophies (PBD) gained traction and increased in practice. BC embraced PBD on projects in the early 2000’s\, and the Canadian bridge code formally adopted PBD in 2014\, which has continued in the coming 2025 bridge code. \nThis presentation will describe the evolution of seismic bridge design and construction in BC and other regions of Canada. It will highlight challenges faced as well as some remaining challenges and opportunities provided through performance-based approaches and network-level considerations. It will show through case studies how functional retrofits can be achieved and how corridors can be assessed for importance in post-earthquake response. \nIt will also provide an overview of the evolution of PBD within our coming 2025 bridge code and will discuss issues and challenges in PBD in practice. It will discuss aspirations for improvements to PBD for structural and geotechnical design\, including needs for refinements in seismic hazard information to better suit PBD of bridges and buildings for the next code cycle. \n  \nPresenter \n\n\n\n\n\nDon Kennedy\nSenior Bridge Engineer\nAssociated Engineering Ltd.\n(kennedyd@ae.ca) \nCAEES-ACGPS Vice-President \n\n\n\n\n\nDon has 40 years of experience in the planning\, design and construction of new bridges\, bridge and structure rehabilitation and seismic retrofit\, bridge evaluation\, forensic investigations into bridge failures. His experience includes Canadian and international engineering experience in earthquake engineering. He has authored papers and presented seminars on seismic design and retrofit\, codes and performance-based design and rehabilitation. During his career he has worked on the design or design reviews of most of the major bridge retrofit projects undertaken in BC since the early 1990’s. He led the retrofit design of the Oak Street\, Knight Street and Mission Bridges\, and provided technical guidance to the Cambie and Granville St Bridge retrofits\, and to a recent seismic resilience assessment of the Highway 99 corridor between Vancouver and the USA border. These projects influenced seismic retrofit practice and policy in BC and Canada. Most recently he has worked with owners and engineers in Ontario and Quebec on seismic projects\, standards and policy\, in part arising from the recent increase in seismic hazard as part of the sixth generation ground motion modelling and hazard mapping in eastern Canada\, and to assist owners in the application and management of performance-based seismic design for new bridges and seismic retrofit projects/ \nDon has contributed to the Canadian Highway Bridge Design Code (CHBDC) for seismic design since 2002 and is the current Chair of TSC 4 for the Seismic design of bridges. He is currently a Director and Vice-President of the Canadian Association of Earthquake Engineering and Seismology. He contributed to the application of performance-based seismic design implemented into the CHBDC in 2014\, 2019 and the coming CSA-S6:25 in summer 2025.
