Which term refers to the installation of a structural reinforcement in construction?

• A. Subvention
• B. Bewehrung
• C. Senkblei
• D. Wasserwaage

Answer: (B)

The term that refers to the installation of a structural reinforcement in construction is "Bewehrung." This is a German word commonly used in the construction industry to denote the process of reinforcing concrete structures with materials such as steel. The purpose of this reinforcement is to enhance the tensile strength of the concrete, which is inherently strong in compression but weak in tension. By integrating materials like steel bars or mesh into the concrete mix, the overall durability and load-bearing capacity of the structure is significantly improved.

The other terms listed are not related to structural reinforcement. For instance, "Subvention" typically refers to a financial grant or subsidy, which does not pertain to construction techniques. "Senkblei" translates to "plumb bob," a tool used in construction for establishing vertical references, while "Wasserwaage" means "level" or "spirit level," used to ensure surfaces are horizontal. Thus, "Bewehrung" is the appropriate choice for describing structural reinforcement in construction.
