In this paper on reinforced concrete rectangular slabs with four edge beams, the influences of the variation of loading conditions, rigidity of edge beams and reinforcements on elastic and plastic behavior of slab, especially mechanism of failure, ultimete, strength and arching action are discussed. For this purpose eight rectangular slabs were tested and the next results were obtained. 1) The ultimate strength of rectangular slab with edge beams is far in excess of that predicted by Johansen's yield-line theory considering only the bending strength. The main reason may be the srching action induced in the slab. 2) The effect of arching action in slab has a tendency to be large, when the edge beam is rigid, the loading condition is nearly uniform. 3) The slabs are divided into the triangular and trapezoid shapes in case of Uniform loading, and the radial shapes in case of concentrated loading at the final failure stage.
