Title: Yield-Line Theory for the Ultimate Flexural Strength of Reinforced Concrete Slabs

Abstract:An outline is presented of the yield-line theory, a lastic theory for the prediction of reinforced concrete slabs, developed by K. W. Johansen. The theory is based on plastic behavior occuring in a pattern of yield lines, the location of which depends on load and boundary conditions. The ultimate flexural strength may be evaulated, even for complex slabs, with limited mathematical effort. The theoretical strengths obtained are in good agreement with experimental results, and generally on the safe side thereof. The use of the theory is illustrated by numerical examples.
