LJB structural engineer, Jim Lintz, and Elias Toubia, an assistant civil engineering professor at the University of Dayton, received an outstanding paper award last month at The Masonry Society’s North American Masonry Conference in Denver.
The paper, titled “In-Plane Loading of Brick Veneer over Wood Shear Walls,” was the result of a research project completed by Lintz while he was earning his master’s degree in civil engineering at the University of Dayton.
The paper described an analytical method for calculating how much in-plane load will be transferred from a wood shear wall to brick veneer by the brick ties that connect the two. It also described the results of applying this method to typical wood shear walls. The results showed that even before the wood shear wall has reached its design capacity, the load transferred to the brick veneer can be strong enough to cause the brick to slide or overturn. The force in the brick veneer is currently not accounted for in engineering design and could cause serviceability issues in the veneer.
The paper also suggested a practical method to prevent the sliding or rocking of the brick veneer. The theoretical results from the paper were consistent with full-scale testing of wood shear walls with brick veneer.
Lintz has been with LJB since 2007 and completed his master’s degree in 2012.
