Understanding Glulam: The structural and architectural capabilities of mass timber
Course Overview In this course, you’ll gain insight into the design and manufacturing considerations involved in using glulam in buildings. As one of the oldest mass timber products used in Canada, glulam offers exceptional flexibility and can be incorporated into a wide range of building types—particularly where curvature and expressive geometry are key. Presenters will outline design and manufacturing strategies for creating efficient structures, showing how glulam can be used not just as columns and beams, but as the primary structure in today’s innovative buildings—whether architecturally driven or focused on value and efficiency. They will also cover the availability of glulam products across Canada and explain how to maximize the value of the timber used. Practical tips will be shared to help designers and specifiers take full advantage of glulam’s attributes in a cost-efficient way. Learning Objectives Participants will learn the design strategies employed when using curvature and geometry in buildings and gain an understanding of what is possible with expressive architecture. Participants will understand the practical constraints of glulam manufacturing, including how to approach the design and specification of glulam members. Participants will learn how different wood species and strength grades are applied in glulam design, and how to use them efficiently for optimal performance. Participants will understand how geometry, fire ratings, and member layups influence the cost-efficiency and design potential of glulam systems.

A Zero Carbon Hybrid Wood Supertall Future
Course Overview With buildings generating 40% of global carbon emissions, we need to achieve net-zero by 2050 to meet the Paris Agreement target and limit global warming to 2°C. Timber sequesters an average of 1.9 metric tons of carbon-dioxide equivalent emissions per cubic meter (Sathre & O’Connor, 2010). While a purely mass timber tall building may not be the most cost-efficient solution, a hybrid structure can maximize the overall use of wood by volume in the most cost-efficient manner. Floor systems in buildings contribute as much as 73% of the environmental impact of a high-rise building’s structure (Lankhorst et al., 2019), making them an excellent target for reducing embodied carbon. DIALOG’s patent- pending Hybrid Timber Floor System (HTFS) takes advantage of the benefits of cross-laminated timber (CLT) combined with pre-stressed concrete to achieve a 12-metre column-free span. The HTFS is proposed as part of our Hybrid Timber Tower, a 105-storey mixed-use prototype that is being evaluated and tested by DIALOG and EllisDon. The prototype structure consists of the hybrid timber floor, combined with a concrete core and an external steel frame. Fire safety is achieved in the floor panels as the exposed wood chars to form a protective layer, while the non-combustible concrete and steel band continues to support the panel. The exposed CLT panels also provide a biophilic appeal, which has shown to support cognitive function as well as physical and psychological well-being (Vidovich, 2020). DIALOG, EllisDon, FPInnovations and other partners have completed the first phase of small-scale testing on over 40 panels. We are scheduled for fire testing of the panels in Ottawa with NRCan this fall with full scale testing of the 12-meter panels starting in late 2022. Learning Objectives Describe how hybrid mass timber systems—such as the Hybrid Timber Floor System (HTFS)—reduce embodied carbon and support zero‑carbon goals in high-rise, mixed-use developments. Explain the structural, fire safety, and performance characteristics of hybrid CLT–concrete floor assemblies, including how charring, concrete bands, and steel elements contribute to long-span capability and code compliance. Evaluate the role of multidisciplinary research, prototyping, and large-scale testing in validating hybrid timber technologies for supertall applications, including their impacts on sustainability, biophilia, and cost efficiency.

Aspen Art Museum: Creating an Innovative Wood Structure
Course Overview The Aspen Art Museum, designed by architect Shigeru Ban, includes a long-span three-dimensional wood space-frame roof. Ban’s charge was to create a wood space frame with spans of more than 50 feet and cantilevers of 14 feet, in a structural depth of 3 feet. The space frame was to have two planes of intersecting diagonal webs of curved members that undulated up and down to touch the planes of the top and bottom chords with no visible connectors. This case study presentation will describe the design and construction of the wood structure, including paths explored but not chosen for the final design. Learning Objectives Articulate the particular demands associated with creating a 3-dimensional space frame entirely in wood. Recognize the advantages and disadvantages of several wood connection strategies in space-frame structures. Be aware of manufacturing capabilities and limitations that influenced the design of the Aspen Art Museum roof structure. Understand the importance of early engagement of manufacturing and engineering partners in the design process for innovative wood structures. Course Video Speaker Bio Gregory R.
