How Engineers Actually Design Wood Frame Shear Walls | Royal
from BUILD BETTER HOMES · host PLIRIS
In this technical episode, Royal dives into how structural engineers analyze and resolve loads in residential construction and why different engineers may produce different structural designs for the same home. We highly advise viewers to also watch the episode on YouTube. The discussion begins with the core principles of structural engineering which are determining loads and resolving loads using the ASCE 7 standard and material-specific design codes. From there, the episode explores several methods used to resist lateral forces such as wind and seismic loads in wood-framed construction.Topics CoveredEngineering Design FundamentalsDetermining loads using ASCE 7Resolving loads using material design codesThe importance of constructability reviewSegmented Shear WallsTraditional method used in most residential designsRequires full-height wall segments with no openingsOften results in multiple hold-downs and higher construction costsPerforated Shear WallsUses the entire wall system despite openingsApplies reduction factors based on window and door openingsCan reduce the number of hold-downs requiredForce Transfer Around Openings (FTAO)Uses straps and collectors to redistribute forces around windows and doorsAllows narrower wall segments to perform structurallyCan significantly reduce foundation and hold-down requirementsPortal FramesPerformance-based system commonly used around garage doorsDeveloped through extensive lab testingAllows large openings with narrow wall segmentsPrescriptive Path vs Engineered DesignPrescriptive path uses standardized tables to design structuresOften limits architectural flexibilityEngineered designs can be more efficient for custom homesAdditional Engineering ConsiderationsUsing gypsum drywall to contribute to shear resistance in wind designMaterial selection and constructabilityValue engineering opportunities between builders and engineersKey TakeawayStructural engineering isn’t about “over-engineering” a home but about determining the load, resolving it efficiently, and ensuring the design can be built in the real world. By understanding the different shear wall systems available (segmented, perforated, FTAO, and portal frames) builders and engineers can work together to reduce unnecessary hardware, simplify construction, and control project costs.Connect With UsIf you’re a builder, developer, or contractor who would like to guest in an episode, feel free to reach out.
