A type of framing that requires diagonal bracing is known as:

The type of framing that requires diagonal bracing is post and beam framing. This method utilizes vertical posts and horizontal beams to create the structural framework of a building. The diagonal bracing is critical in this system as it helps to provide stability and support, preventing lateral movement and ensuring overall rigidity. The use of diagonal bracing allows for larger open spaces and lends strength to the structure, making it particularly advantageous in areas where wind resistance is a consideration.

In contrast, the other methods listed generally do not require diagonal bracing in the same manner. King post framing, for instance, often deals with trusses and may use other methods of stabilization. Balloon framing focuses on using continuous studs from the foundation to the roof but does not inherently rely on diagonal bracing for its stability. Platform framing is the most common method used in residential construction today, involving framing each floor as a separate platform and typically relying more on sheathing for structural integrity rather than diagonal bracing. Each of these framing methods has its unique applications and advantages, but it is the post and beam system that specifically necessitates diagonal bracing for maintaining structural strength and stability.
