Which type of buildings have outer walls that are typically non-loadbearing?

Framed buildings are characterized by their construction methods, where the outer walls are often non-loadbearing. In these types of structures, the primary support for the building's weight is provided by the frame itself, typically made of wood or metal. The exterior walls serve more as a barrier against the elements rather than structural elements that bear weight.

This design allows for greater flexibility in architectural design, such as larger windows and open floor plans, since the walls can be placed or modified without compromising the structural integrity of the building. In contrast, other building types, such as heavy timber or brick-joist buildings, often have walls that contribute to the overall load path and structural support, making them loadbearing. Understanding these characteristics is crucial for fire officers when assessing building integrity and fire behavior in emergencies.
