Detailing for Wood Shrinkage
Douglas R. Steimle, PE, Schaefer
For condominiums, apartments, hotels and dormitories, multi-story wood construction is viewed by many as a way to achieve higher density at lower cost, while reducing the project’s carbon footprint. One of the challenges, in designing these taller buildings, is how to calculate and address wood shrinkage, which occurs as the wood dries from its ‘green’ state to its in-service equilibrium state. This session will examine shrinkage associated with wall and floor design, and demonstrate how to minimize effects of both shrinkage and differential movement with proper detailing. Discussion will include how to prevent shrinkage-induced issues such as drywall cracking, window frame wracking, and compromised plumbing lines.

Douglas R. Steimle, PE is a senior level structural engineer with 17 years of experience at Schaefer, a national structural engineering firm headquartered in Cincinnati, Ohio. He is a recognized expert in the design of tall wood and hybrid-frame buildings for multi-story mixed use, residential, and hospitality buildings.

Comparative Life Cycle Assessment: Multi-Story, CLT Apartment in Quebec
Blane Grann, MSc, FPInnovations

Cross laminated timber (CLT), in combination with other engineered wood products, is creating new opportunities for the use of wood as a structural material in taller building systems. This presentation examines the results of a life cycle assessment (LCA) comparing the environmental performance of a multi-story CLT apartment building in Quebec with a similarly designed concrete slab building. While the carbon benefits related to the use of wood in building systems has been well documented, LCA also highlights potential trade-offs in other impact categories. Results from this assessment underscore the importance of adopting LCA in the design phase, rather than as a post-hoc assessment tool, to identify specific opportunities to improve life cycle environmental performance.

Blane is a Scientist in the Durability and Sustainability group at FPInnovations, where uses life cycle assessment to explore environmental indicators in the forest products sector. Driven by a sense of adventure, a deep interest in environmental systems thinking, and inspiration from the adoption of life cycle thinking to address environmental issues at the European policy level, he recently pursued his master’s degree at the Norwegian University of Science and Technology in the field of Industrial Ecology.

An Introduction To the Structural Design Of Post Frame Buildings
Dr. Harvey Manbeck, PE, National Frame Building Association

This program begins with an overview of post-frame building systems and key concepts for their structural design. Information is presented from a conceptual as opposed to equation/computational standpoint. Design methods for post-frame systems with and without diaphragm action will be discussed, with a focus on the former. The presentation will show how a simple yet powerful and readily available computer program, DAFI, determines the proportion of design lateral loads that are carried to ground by the individual post frames and the proportion carried to ground by the roof diaphragm and shear walls. The program then shows how the isolated post foundations are designed to resist lateral and uplift forces.
