Final answer:
Falsework is the correct term for temporary shoring, bracing, or formwork used to support incomplete structural elements during construction, different from a buttress, which is a permanent architectural feature.
Step-by-step explanation:
The term falsework can be defined as temporary shoring, bracing, or formwork used to support incomplete structural elements during building construction. While a buttress in architecture is a projecting structure that reinforces or stabilizes a wall or building according to James Terry, it is not a temporary structure but rather a permanent part of the building's design. On the other hand, scaffolding is a temporary structure used to support workers and materials during the construction or repair of a building. Reinforcement refers to materials like steel bars or fibers that are added to concrete to increase its strength.
