A load-bearing wall is a structural element that is integral to the stability and support of a building. These walls are designed to carry and transfer loads from the roof, floors, and other structural elements down to the foundation. Unlike non-load-bearing walls, which serve primarily as partitions, load-bearing walls are crucial for maintaining the structural integrity of a building.

Key characteristics of load-bearing walls in Australian commercial construction include:

1. Material: They are typically constructed from robust materials such as reinforced concrete, steel, brick, or masonry to withstand significant loads.

2. Design and Engineering: Load-bearing walls are carefully designed and engineered to meet specific load requirements, taking into account factors such as building height, weight distribution, and environmental conditions.

3. Regulatory Compliance: They must comply with the Australian Building Codes and Standards, which dictate the structural requirements and safety measures for construction projects.

4. Placement: These walls are strategically placed within the building's layout to effectively distribute loads. Their location is often determined during the architectural and engineering design phases.

5. Modification Restrictions: Alterations to load-bearing walls require careful consideration and often necessitate the involvement of structural engineers to ensure that any changes do not compromise the building's stability.
