Abstract
The plastic design of steel structures has several advantages over the elastic design, of which the most important are simplified procedures, savings in the cost, and more realistic representation of the actual behavior of steel structures [1.1]. These advantages are due to the fact that the plastic design fully uses the important property of steel called ductility. This chapter will focus on the effects of ductility of the steel on the behavior of steel structures and show the benefits of the plastic methods that are derived from this property. To demonstrate the benefits of ductility, we will present two examples: first a hot-rolled section with residual stresses and second a plate with a hole. For both examples, the material is idealized to have an elastic-perfectly plastic stress-strain behavior as shown in Fig. 1.4.
