A vertical member that provides intermediate support for a girder is known as a ____________.

The term "post" refers to a vertical structural element that provides support in various types of construction, particularly in supporting girders. A post is typically designed to bear weight from beams or girders above and transfer that load down to a foundation or other structural member below.

In residential building construction, posts are commonly used in places where walls may not support a load directly, allowing for more open layouts while still maintaining structural integrity. Posts can be made of different materials, such as wood, steel, or concrete, depending on the design requirements and load factors.

The other terms, while they describe vertical or diagonal members in construction, do not accurately match the definition given in the question. For instance, a stud is primarily used in framing walls and provides support for finishes rather than serving as intermediate support for girders. A column usually refers to a standalone structural vertical member that supports load from above but may not fit the description of intermediary support specifically. A brace, on the other hand, is typically used for stabilization and resisting lateral forces rather than providing vertical support to a structure. This understanding clarifies why "post" is the most appropriate choice for describing a member that supports a girder.
