Abstract
In this paper, yield line theory is used to analyze regular slabs for different nine edge conditions. Two approaches are used for the computation of ultimate load-carrying capacity of a reinforced concrete slab concerning yield line theory. One is an energy method which uses the principle of virtual work and the other, an equilibrium method, which study the equilibrium of diverse part of the slab formed by the yield lines. The yield line theory is an upper bound theory and hence which pattern gives lowest load carrying capacity is the governing pattern. Finally equations are formulated by using yield line theory which are simple to apply.
