Which wall type is designed to add stiffness to resist lateral forces?

• A. Partition Wall
• B. Party Wall
• C. Veneer Wall
• D. Shear Wall

Answer: (D)

When a building faces wind or earthquake forces, you need elements that provide stiffness in the vertical plane. A shear wall is built to do exactly that: it acts as a stiff panel that resists horizontal shear and transfers those forces down to the foundation, reducing sway and deformation. Other walls serve different roles: partitions are non-structural divisions; party walls mainly separate adjacent properties and aren’t designed to carry lateral loads for the entire building; veneer walls are thin facades that rely on a backing wall for strength and don’t provide significant lateral stiffness themselves. So, the wall type designed to add stiffness to resist lateral forces is the shear wall.
