Steel is the most widely used component in the construction of buildings and structures. There are many advantages of steel over concrete. Its important properties include recyclability, increased durability, and low maintenance. The design of steel structures typically consists of a two-step analysis and verification procedure. The first step is to evaluate the internal forces and displacements based on the principles of equilibrium and compatibility. In the second step, these internal forces and displacements are compared against corresponding resistance, stiffness and ductility values to ensure structural safety and fitness-for-purpose. Plastic analysis is a method that determines the collapse behavior of structures on the basis of cross sections under proportionally increasing loading. This book examines the analysis and design of steel structures. It is a vital tool for all researching or studying these structures as it gives incredible insights into emerging trends and concepts of civil engineering. Its extensive content provides the readers with a thorough understanding of the subject.
