Which section would provide the criteria used to assess structural performance under expected loads?

• A. Material Condition
• B. Major Design Conditions
• C. Design Outline
• D. Maintenance Conditions

Answer: (B)

When assessing how a structure should behave under the loads it is expected to carry, the section that covers major design conditions is the one that provides the criteria. This part lays out the load scenarios the structure must resist, how those loads are combined, and the acceptance limits for performance—such as allowable stresses, deflections, crack widths, durability, and stability. In short, it translates anticipated service conditions into concrete design requirements that the structure must meet to remain safe and functional throughout its life.

Materials-focused sections describe the state and properties of materials, not how performance is judged under loading. A design outline tends to be a broad plan rather than the specifics of performance criteria. Maintenance-related sections deal with upkeep and condition monitoring, not how the structure should perform under expected loads.
