Plastic Design of Steel Structures
Plastic design of steel structures may assume different degrees of complexity and sophistication. It is often used in the design of pitched‐roof portal frames. The methods of plastic analysis can be based on: the static theorem or maximum principle; the kinematic theorem or minimum principle. This chapter exemplifies the relevant aspects of plastic design of steel structures, with reference to EC3. It provides procedures for the plastic analysis of pitched‐roof portal frames, in which the global analysis is first order. The problem is simplified since it deals only with material non‐linearity, either from a pre‐design point of view using simple approximate methods, or in the context of an incremental elastic‐plastic computational analysis. The chapter presents and discusses the procedures for the incorporation of second order effects. Reference is made to simplified methods and to more thorough computational analysis, illustrated with simple examples.
