| Parameter | LSD | WSM | |-----------|-----|-----| | Basis | Probability & limit states | Elastic behavior only | | Safety factor | Multiple partial factors | Single factor of safety (typically 1.67 for steel) | | Member economy | 15–25% lighter sections | More conservative, heavier | | Handling of buckling | Explicit (using Perry-Robertson formulation) | Empirical or ignored | | Deflection check | Separate SLS check | Often combined with stress check | | | More calculation steps, iterative | Simpler but unrealistic for slender members |
