Exposed Wood in Fire-Resistive Applications

David Barber, Arup

For buildings, the fire resistance of structural elements is a code-stipulated requirement often dictated by the construction type chosen rather than building materials used. Wood structures are unique in that they can be unprotected while still providing a level of fire resistance. However, both designers and jurisdictions tend to be unfamiliar with this approach. This presentation will cover the use of a variety of exposed structural wood products (solid sawn lumber, nail-laminated timber, glue-laminated timber and cross laminated timber) in different fire-resistant applications for construction Types III, IV and V. Discussion will include implementation of char calculations, considerations for connections, and information on when calculations or fire tests are required for proving fire resistance in these scenarios. With a better understanding of the challenges and potential solutions, attendees will be able to confidently pursue exposed wood for their projects.

David is a Principal with Arup, based in Washington, DC, where he works as a fire protection engineer. He has been involved in the research and design of timber structures for over 20 years, assisting with testing and development of new timber technologies, authoring fire safety design guides for construction, working with wood product suppliers and completing fire safety design for mid-rise and high-rise timber buildings. David assists architects, engineers and contractors with timber designs, and also works with timber product developers. He is currently working with the project teams for the two US Tall Wood Building Prize Competition winners, Framework in Portland, Oregon and 475 W18th Street, in New York.
