ROOM 1 – Mass Timber Design Topics

MORNING SESSION 9:45 AM

Correcting Misperceptions of CLT Fire Performance

David Barber, Arup

This presentation aims to answer questions commonly asked about cross-laminated timber (CLT) fire performance, including delamination and fire-resistance ratings, and how these issues related to low- and mid-rise buildings within the size limits of the current International Building Code (IBC) vs. high-rise buildings. Because CLT is relatively new in the US, designers often have to explain the fire design of their structure in much more detail than is required for typical construction materials, even for code-compliant buildings. This session should equip designers with a better understanding of the code requirements, relevant and applicable CLT design methods, test standards and available testing related to CLT fire performance.

David is a Principal with multi-disciplinary engineering firm Arup, where he specializes in the fire safety of mass timber buildings. For over 20 years, he has assisted with fire testing, helped develop new timber technologies, authored fire safety design guides for construction, and implemented fire safety solutions for mid-rise and high-rise timber buildings. With resurgent interest in mass timber construction, David relocated to Washington to assist Arup in developing a US-based team that works with researchers, architects and developers in the fire safety of timber structures. He is currently working with project teams on mass timber buildings throughout the US and globally.

Knock on Wood: Acoustical Solutions in Mass Timber Structures

Denis Blount, CTS-D, Associate, Arup

The use of mass timber in multi-family and commercial buildings presents a complex set of acoustic challenges. While laboratory measurements of the impact and airborne sound isolation of traditional building assemblies, such as concrete, steel, and light wood-frame, are widely available, fewer resources exist that quantify the acoustic performance of mass timber assemblies, including CLT and NLT systems. Furthermore, acoustical professionals are not typically retained for mass timber projects, placing the acoustic responsibilities on the design team. This presentation will review common mass timber assemblies and acoustical rules of thumb for architects and designers. Topics will include detailing strategies, options for eliminating flanking paths, and best-practices for achieving good acoustic performance in mass timber buildings.

Denis Blount leads the Acoustics, Audiovisual and Theater Consulting team in Arup’s Seattle office. With a background in engineering and music, he is uniquely positioned at the intersection of acoustics, technology and architectural design. Throughout his career, Denis has worked closely with architects, engineers and clients covering a wide range of building sectors.

Enclosure Design for Mass Timber Buildings

Colin Shane PE, MEng, PEng, RDH Building Science Inc.

Larger and taller mass timber buildings are becoming common in North America. These buildings typically utilize CLT or NLT panels, glulam beams and columns, and new engineered timber components to meet the structural and fire requirements associated with greater heights. With these larger wood structures and heavier timber components comes the need for efficient building enclosure assemblies that can be installed quickly on tight sites and are in many cases new and unique to the industry. Prefabricated building enclosure elements are now also commonly used. This presentation shares guidance on building enclosure design and detailing best practices for mass timber buildings. It includes case studies and lessons learned from the design, construction, and monitoring of enclosures for recently completed projects.

Designing with Glulam and Timber: The Art of Engineering Really Cool Structures

Jim DeStefano, PE, AIA, F.SEI, DeStefano & Chamberlain

For architecturally exposed structures, nothing beats the look and feel of timber when drama is needed and a more mundane structure just won’t do. Glulam has long been used as an architectural element, but there’s a new tradition emerging that combines glulams and traditional timber frame construction with mass timber panels. The engineering of a dramatic glulam structure is as much an art as it is science, particularly the design of timber connections that complement the architecture. This entertaining and informative presentation will cover the basics of designing and engineering such a building. Topics will include a review of traditional and contemporary approaches to glulam construction, connection design, and design and detailing considerations such as durability and fire resistance.

Jim is president of DeStefano & Chamberlain Inc. located in Fairfield, Connecticut. He is a structural engineer and licensed architect with 40 years of experience designing timber structures.
