The C.E.B. concepts of Limit States are illustrated, as well as the choise of the verification in the space of load effects. Safety formulation based on partial coefficients is explained, with particular reference to the problem of nonlinear analysis of statically indeterminate structures and to the uncertainity of the statical model. A ductility condition for linear analysis with redistribution is described and the criteria of its derivation are outlined. The criteria for serviceability limit states are briefly summarized, with reference to cracking and to deflections.
