Which wall is the strongest?

Strongest wall type depends on criteria but generally for structural strength and durability, reinforced concrete walls are among strongest, capable of supporting heavy loads and resisting earthquakes, wind, and fire. Concrete block walls filled with rebar and grout, known as reinforced masonry walls, are also very strong and commonly used for foundations, retaining walls, and commercial buildings. Among residential walls, structural insulated panels and insulated concrete forms create very strong, energy efficient walls that resist high winds and impacts. Brick walls are strong and durable but rely on mortar. For sheer lateral strength to resist earthquakes and hurricanes, shear walls made of plywood over wood studs or concrete are designed to be strongest. In terms of load bearing capacity, load bearing walls are stronger than partition walls. Retaining walls designed to hold back soil need to be strongest in terms of lateral pressure resistance, typically reinforced concrete. So reinforced concrete wall is generally considered strongest overall for strength, durability, and disaster resistance.
