NBC 2020 – Changes to Seismic Design Provisions
This session will cover key changes in the provisions for seismic design of new buildings in NBC 2020 as compared to NBC 2015 (BCBC 2018, VBBL 2019), with background on each of the changes. The focus will be on Part 4 of the code (Section 4.1.8 Earthquake Load and Effects), with a brief discussion on Part 9.
Speaker
John Sherstobitoff, P.Eng.
John is a structural engineer with over 35 years’ experience relating to the structural and seismic analysis and design of both infrastructure and buildings. He has worked on a wide variety of new projects, as well as hundreds of seismic upgrade projects developing and incorporating innovative schemes, such as Canada’s first base isolated building. Many of these projects involved extensive use of non-linear dynamic analysis, including non-linear soil structure interaction. He is past Chair, Standing Committee on Earthquake Design (SC-ED), NBCC and current Chair of SC-ED’s Task Group on Resilience and Performance Based Design and Working Group on Seismic Isolation and Supplementary Energy Dissipation.
Structural and Fire Considerations for Encapsulated Mass Timber Construction
This session will provide an overview of structural and fire provisions for encapsulated mass timber construction (EMTC). BC recently made changes to the 2018 BCBC, allowing encapsulated mass timber construction for building up to 12 stories or 42m in height. The Architectural Institute of BC and Engineers and Geoscientists BC jointly produced practice guidelines: Encapsulated Mass Timber Construction Up to 12 Storeys which cover considerations for professional services for both architects and engineers. This presentation will also provide a high-level overview of the new guide and code changes.
Speaker
Grant Newfield, P.Eng., Struct.Eng.
A respected champion for innovation in wood design and the increase in the use of mass timber systems, Grant’s work has pushed the height limits of traditional wood-framed structures both in practice and through code development. He also leads high-rise and developer-oriented projects, considering costs and buildability to develop the right solution to maximize pro formas and deliver the architectural vision. As a mass timber specialist, Grant is a sitting member of the National Building Code of Canada (Part 4) and Canada’s Wood Design Standard (CSA086) for many years. Grant has been at the forefront of code changes that have advanced the adoption of wood and mass timber across Canada. Grant has an exceptional appreciation of how mass timber systems integrate with other structural materials, and how connections and ease of assembly are key to the success of any mass timber project.
