Introduction The design of steel structures has evolved significantly over the last century, moving from empirical methods to rigorous mathematical modeling. At the forefront of this evolution is the Limit State Design (LSD) method, also known as Load and Resistance Factor Design (LRFD) in North America. This design philosophy ensures that structures remain fit for purpose throughout their intended lifespan by addressing the probability of failure in a rational and scientific manner. This document explores the fundamental principles, methodology, and applications of Limit State Design in modern structural steel engineering. 2. The Philosophy of Limit State Design Unlike the older Working Stress Design (WSD) or Allowable Stress Design method—which ensured stresses remained well below yield limits by applying a single factor of safety—LSD acknowledges that different types of loads possess different degrees of uncertainty and variability.
