Yield line theory is a productive method for deciding the breakdown heap of strengthened concrete slabs. The yield-line hypothesis is an adaptable outline strategy, particularly when orthotropic and inhomogeneous properties, gaps and unique bolster conditions, must be considered. In the 1960s yield line hypothesis was the subject of extensive enthusiasm for the UK, as prove by a whirlwind of papers and monographs, including an uncommon distribution issued by Magazine of Concrete Research. In the event that the tomahawks of turn for two slab parts are not at the same profundity measured from the section surface, the relative relocation intermittence is no more opposite to the yield line. One disputable and minimal comprehended part of Johansen 's yield line hypothesis is the idea of nodal forces. It uses Yield Line Theory to investigate failure mechanisms at the ultimate limit state. Thus, work done in yield lines rotating means work done in loads moving. Yield Line Design leads to slabs that are quick and easy to design, and are quick and easy to construct.
Key words: Yield line, design, slab, concrete structures.
Yield line theory is a productive method for deciding the breakdown heap of strengthened concrete slabs, and it pre-dates limit examination. The term 'yield line ' (in Danish: 'brudlinie ', truly signifying 'line of crack ') was authored in 1921 by Ingerslev to depict lines in the slabs along which the twisting minute is steady .
