What does the acronym BSDS stand for?

• A. Bridge Seismic Design Specifications
• B. Building Seismic Design Standards
• C. Bridge Structural Design Standards
• D. Basic Seismic Design Specifications

Answer: (A)

The phrase Bridge Seismic Design Specifications describes a formal, detailed set of requirements for designing bridges to resist earthquakes. Here, “Bridge” identifies the structure type, “Seismic Design” specifies the earthquake-related design focus, and “Specifications” indicates a technical, prescriptive document. This exact combination defines a bridge-oriented, detailed guide for seismic design, which is why it is the best fit. Alternatives shift the domain (Building vs Bridge), the scope (Standards vs Specifications), or the emphasis (Basic vs Seismic), so they don’t match the intended document type as closely.
