Final answer:
The framing system that uses fewer but larger framing members spaced farther apart is the post-and-beam framing system, suitable for creating open spaces in a structure.
Step-by-step explanation:
Post and beam structures are built with vertical beam posts and horizontal beams. Metal brackets and steel plates join the timbers and hold the structure together, but they aren't always visible. In some cases, they're decorative, but in other cases, they're structural and placed out of sight.
The framing system that relies on fewer but larger pieces of framing members spaced farther apart than those used in conventional framing is known as a post-and-beam framing system. This type of construction is often used when creating open interior spaces and is a departure from common methods like platform or balloon framing, which use smaller, more numerous pieces. In post-and-beam systems, the load is carried by large beams and posts, which requires less structural material overall yet allows for a sturdy build.
