A load-bearing wall is a structural part of a building: it supports weight from above and transfers that load toward the foundation. Understanding this load path helps explain how buildings remain stable, how walls differ in their roles, and why construction methods change as buildings grow taller.
A load-bearing wall (also called a bearing wall) is an active structural element that carries the weight of building elements above it. The wall conducts that weight downward to a foundation, which transfers it into the ground. This route of forces is called a load path.

What is a load-bearing wall?
It is an active structural wall that carries weight from elements above it and transfers that load toward the foundation.
What is a load path?
A load path is the route by which building forces travel through structural elements to the foundation and then into the ground.
How does a flying buttress help create an open interior?
It transfers more of a building's weight outward to an external support, reducing the share that must be carried by central bearing walls.
What are the main plates in a platform-framed wall?
The top plate and bottom plate hold the wall studs. The bottom plate may also be called the base or floor plate, and the top plate may be called the ceiling plate.
Why are deep piles used for some skyscrapers?
Piles help anchor the building's foundation to bedrock or strong ground below, supporting the very large loads of a tall structure.
Quiz questions
What is the primary structural role of a load-bearing wall?Answer: It carries loads from above and routes them toward the foundation.
How does a curtain wall differ from a load-bearing wall?Answer: It encloses the building and transfers its own loads to the structural system.
What effect did flying buttresses have on Gothic architecture?Answer: They shifted more weight outward, helping make more open interiors possible.
What is the role of a wall sill plate in platform framing?Answer: It supports the framed wall, connects it to the base, and is bolted to the foundation.
Why did load-bearing walls become less common in large commercial buildings as skyscrapers developed?Answer: Steel framing suited large buildings better, while bearing-wall construction had limits at that scale.
