Limit State Design principles are codified worldwide. Most contemporary structural steel design codes are based entirely on this philosophy:

Loads (Dead, Live, Wind, Earthquake) are multiplied by factors to account for the possibility that the actual loads might exceed the nominal design values. For example, a common load factor for in many codes is 1.5 . Essential Design Components Limit State Design principles are codified worldwide
LSD uses a format to account for uncertainties in both load and material strength. Limit State Design of Steel Structures | PDF - Scribd For example, a common load factor for in many codes is 1
Historically, structural steel design relied on the Allowable Stress Design (ASD) method. ASD ensures that the stresses calculated under working loads do not exceed a fraction of the material's yield strength. While straightforward, ASD does not account for the non-linear behavior of steel or the varying uncertainties of different load types.
