Which design approach uses factors applied to loads and resistances to ensure performance across multiple limit states?

Designing to ensure performance across multiple limit states by applying factors to both loads and resistances targets a specified level of reliability for all potential behavior modes. In this approach, load effects are amplified by load factors and the structural strength is reduced by resistance factors, so the design requirement is a factored resistance exceeding factored loads for each limit state (strength, serviceability, fatigue, stability, etc.). This balance across uncertainties in material strength, workmanship, and loading is what makes Load and Resistance Factor Design the method that consistently governs performance under varied conditions.

Other options describe different concepts: one method focuses only on increasing loads without adjusting resistances, which doesn’t secure uniform reliability across limit states; Lane Loading refers to standard vehicle loads for roadway design, not a design philosophy; Lighting Standard is unrelated to structural design.
