Yield line theory, a plastic theory for the prediction of ultimate flexural strength of reinforced concrete slabs, has been developed by Prof. K. W. Johnsen. The theory is based on plastic behaviour occurring in a pattern of yield lines, the location of which depends on loading and boundary conditions. This paper has used the distribution of reinforcement as dictated by the elastic theory so that the redistribution of moments after crack formation is minimum.
