In which type of framing are the structural members larger and more widely spaced?

The correct answer is post-and-beam framing. This type of framing is characterized by the use of larger structural members, such as beams and posts, which are set farther apart than in other framing methods. This design allows for more open floor plans and fewer supporting walls, resulting in greater flexibility in the interior layout of a structure.

Post-and-beam framing relies on the vertical posts to support horizontal beams, creating a sturdy and strong framework. This approach is ideal for buildings that require larger spaces or that have design features like vaulted ceilings, as the larger members can support significant loads while offering aesthetic appeal.

In contrast, balloon framing has smaller, continuously running studs from the foundation to the roof, and platform framing features shorter studs that are connected at each level, which don’t provide the same degree of spacing or structural size found in post-and-beam construction. Sub-form is not a recognized method for framing buildings in this context, focusing instead on other aspects of construction.
