A joint research project of APA – The Engineered Wood Association, University of British Columbia (UBC), and USDA Forest Products Laboratory was initiated in 2009 to examine the variations of walls with code-allowable openings. Test results from the (8' x 12') full-scale wall configurations, in conjunction with the analytical results from a computer model developed by UBC, were used to develop and refine rational design methodologies in accordance with the International Building Code (IBC). This presentation provides an update of that research with a focus on asymmetric piers and multiple openings. Rational design methodologies in accordance with the IBC will be shared.

Learning Objectives:

  1. Investigate past and current methods for determining force transfer around openings for wood shear walls.
  2. Compare the effects of different sizes of openings and full-height piers, and their relationships to the three industry standards for calculation of force transfer around openings.
  3. Assess new design methodologies for accurately estimating the forces around multiple openings with asymmetric piers.
  4. Estimate the deflections for shear walls designed using the force transfer around openings design method.
