Abstract: In the present study the experimental investigations were carried out on two way slabs for simply supported condition. A total four slabs spanning over 940mm with an effective depth of 74mm were tested under a single point loading to understand the flexural behaviour of two way slabs. The effect of increase in grade of concrete and percentage of reinforcement were studied on the first crack load, ultimate load and on their corresponding deflections. The combined load deflection behaviour of slabs was plotted and arrived at Energy absorptions and ductility indices. The comparison of ultimate load to the Johanssen yield load was also carried out and the relevant conclusions were reported.
