Designing for Durability and Safety: Seismic, Fire, and Construction Considerations for Mass Timber Connections (Recording)
Presenters review key provisions from ASCE 7, IBC, and CSA O86:24, and share findings from recent testing on concealed beam hangers and steel fasteners. Attendees learn how to detail connections that perform reliably under seismic drift, fire exposure, and fluctuating environmental conditions common on construction sites. Learning Objectives:
By the end of this webinar, participants are able to:
- Interpret Code Requirements Identify and apply relevant provisions from ASCE 7, IBC, and CSA O86:24 related to seismic deformation compatibility, fire resistance, and steel fastener performance in mass timber construction.
- Evaluate Testing Methodologies Describe how experimental testing - such as fire resistance and cyclic deformation tests - can validate connection performance and inform design decisions.
- Detail for Performance and Durability Explain key detailing considerations for mass timber connections to address seismic drift, fire exposure, and environmental effects during construction.
- Apply Engineered Design Strategies Integrate tested connection systems and fastener specifications into mass timber designs to enhance safety, code compliance, and long-term durability.
