Yield Behaviour of Three Edge Simply Supported Two-Way Slab Under Concentrated Loading
2021
Failure of slab takes place forming a specific mechanism with flat facets between linear plastic hinges at which relative rotation occurs, called yield-line ring. The present study has made an attempt to study the behaviour of two-way RCC slab of size 1 m × 1 m of thickness 0.1 m at failure, simply supported on three sides and fourth side being free, under a centrally applied concentrated load. In total three-slab specimens having compressive strength of concrete, percentage of reinforcement and grade of reinforcement being kept constant are tested as an explorative test. Formation of yield lines is observed and collapse load has been determined. Johansen’s yield-line theory has been adopted to predict the upper-bound collapse load of the slabs. The theoretical prediction is compared with the experimental values. Certain discrepancy between theoretical and experimental values is observed. The load deflection relationship has been observed till the collapse of the slab.
