Structural Load Bearing Explanation

What happens here

The presenter emphasizes that building strength is not solely dependent on material strength, but on how systems are connected. He clarifies that in both cases, the exterior cladding (brick veneer or siding) and the outer leaf of a cavity wall are primarily for water and impact resistance and do not contribute to bearing the roof loads. Instead, the structural block wall in the 'EUROPE' model and the stud wall in the 'USA' model are the components that handle all the load from the roof and upper floors. He uses a trowel to point out how the brick veneer is separate from the structural block wall.

Goal: Explain how structural loads are handled in different house construction types.
