Abstract
In this paper the authors present full account of an experimental study conducted on a model of relatively large size R.C model consisting of single shear wall and a portion of coupling slab subjected to the effect of lateral load, which was simulated by uniform displacement of the line of contra flexure. The research work carried here is aimed at studying the flexural behavior, particularly the extent of redistribution of stress in post elastic range and the suitability of Direct Ultimate Load design method for the design of such slab. Due to high concentration of bending stresses, shear and torsion caused by both the gravity as well as wind loading, possibility of failure of these buildings because of punching of walls through the slabs at their inner faces is profound and therefore it is an area of active research for last three decades. end. Results show that fibre reinforcement up to 1.5% has pronounced favorable effect on the strength attempt has been made to improve the strength of wall – slab junction by addition of circular steel fibre reinforcement the junction. Beyond this the effect is negligible.
