CLICK TO TAKE ECOURSE: Resolving Wood Shear Wall Design Puzzles with Force Transfer Around Openings (DES415)


This presentation provides an overview of the Force Transfer Around Openings (FTAO) shear wall design approach, recent research in this area, and a side-by-side comparison of design results between segmented, perforated, and FTAO design methods. This methodology is based on a joint research project of APA – The Engineered Wood Association, University of British Columbia (UBC), and USDA Forest Products Laboratory that examined variations of shear walls with code-allowable openings.  The study evaluated internal forces generated during testing and assessed the effects of opening sizes, full-height pier sizes, and different construction techniques, including the segmented, perforated, and FTAO methods. Asymmetric piers, multiple openings, and C-shaped sheathing were investigated and rational design methodologies in accordance with the International Building Code have been created.  


Learning Objectives
1.    Participants will investigate past and current methods for determining force transfer around openings for wood shear walls through discussion of the joint research project of APA – The Engineered Wood Association, the University of British Columbia (UBC), and the USDA Forest Products Laboratory (FPL).
2.    Participants will compare the effects of different opening sizes, full-height pier sizes, and their relationships to the three industry shear wall approaches by illustrating use of the segmented, perforated, and FTAO methods.
3.    Participants will observe how the study examined internal forces generated during loading by reviewing full-scale wall test data as well as analytical modeling performed in determining statistical accuracy.
4.    Participants will conclude that research results obtained from this study can be used to support different design methodologies in estimating forces around openings accurately.

Jared S. Hensley, P.E. holds a Bachelor of Science in Architectural Engineering with an emphasis in structural design from the University of Wyoming. An expert in residential and commercial design utilizing engineered wood products, Jared spent eight years as consulting Structural Engineer and is a registered Professional Engineer in Colorado, Wyoming and Washington. His design and construction management experience includes structural design for new and renovated buildings incorporating steel, masonry, timber and concrete, as well as acting as a consulting engineer for rough framing inspections for several large residential and commercial builders in the greater Denver area. Jared joined APA in the spring of 2015 and is currently an Engineered Wood Specialist representing the Pacific Northwest territory.



1.5 hours of education credits will be awarded.
