Plastic Design of Steel Structures
Plastic design of steel structures may assume different degrees of complexity and sophistication. In this chapter, methods of analysis and structural models based on beam theory are presented. Plastic analysis of structures can be carried out with different levels of sophistication. The methods of plastic analysis can be based on the static theorem or maximum principle, and the kinematic theorem or minimum principle. Plastic design of steel structures is often used in the design of pitched‐roof portal frames. The chapter describes the verification procedures for members and components that contain potential plastic hinges, being an essential feature of plastic design. General criteria for the verification of the stability of members with plastic hinges, as well as rules for bracings, are presented. Because of the complexity of such verifications and potential loss of resistance and therefore economy, a common procedure is to prevent out‐of‐plane buckling by the use of adequate bracings.
