Parametric study of timber shear walls
Timber shear walls comprise the vertical element of the lateral force resisting system in many low-rise buildings in North America. A typical shear wall consists of a solid panel product connected to a light timber frame with either a dowel-type fastener, such as nails, or elastomeric adhesives. …

Monotonic and Cyclic Performance of Long Shear Walls With Openings
… and window openings on long timber framed shear walls was the subject of this thesis. Four different wall configurations containing various openings and one control wall with no openings were tested to examine ultimate load capacity and stiffness. All walls were forty feet in length and contained …

Investigating the Performance of Wood Portal Frames as Alternative Bracing Systems in Light-Frame Wood Buildings
Light-frame shearwall assemblies have been successfully used to resist gravity and lateral loads, such as earthquake and wind, for many decades. However, there is a need for maintaining the structural integrity of such buildings even when large openings in walls are introduced. Wood portal frame …
