The preceding chapter was concerned with basic assumptions and theorems used in the plastic analysis and design of steel structures. In the following two chapters we shall present two basic methods of plastic analysis and design. In this chapter, we shall present the plastic analysis and design technique known as the “equilibrium method,” based on the lower-bound theorem. In the next chapter, the plastic analysis and design technique known as the “work method,” based on the upper-bound theorem, will be presented.
