In the realm of structural engineering, safety and economy are perpetually at odds. For decades, designers relied on the Allowable Stress Design (ASD) method—a single-factor approach that bundled uncertainties into a blanket safety factor. While effective, ASD often led to over-engineered, costly structures or, worse, hidden vulnerabilities.

Step 2: Load Combinations (ULS) The code prescribes critical combinations, e.g.: over-complex for routine industrial buildings.
The limit state design of steel structures is not merely an academic exercise—it is the bedrock of modern structural safety. By acknowledging that structures can fail in multiple ways (yield, buckle, fatigue, deflect, vibrate) and assigning rational partial safety factors, engineers achieve both economy and robustness.
