	Summary:
	Calculation of cross section forces reinforced concrete slab, in practice often is done according to the Theory of elasticity(ТЕ). In cases where the dimensioning section should be done according to the theory of critical load then the solution static actions, at the moment just before the break, should be find from the inelastic solutions. Methods for the calculation of reinforced concrete structures at the time of failure, developed to date are based on the solutions of Theory of plasticity(ТP). In this connection, with a reinforced concrete slab, the paper describes the particular case, which concerns the formation of the plastic hinge line, known as the Yield line theory(YL). With in the (YL)are described kinematic and static theorem. For examples of simply supported and fixed reinforced concrete slabs are defined upper and lower load limit value. In the software package Sofistik there are analyzed examples of reinforced concrete plate in the form of defining the shape line fracture in comparison to the realistic forms of line fracture.
