Abstract: A yield line method is developed to analyze reinforced concrete slabs-on-grade to determine collapse loads. The particular cases discussed are: (1) A one-way slab with a line load at mid-span; (2) a slab with a central load; (3) a slab with a load at a free edge; and (4) a slab with a load at a free corner. For each case, an expression for the collapse load is given in terms of material and geometric parameters. Plots of collapse load magnitude versus a load distribution parameter are presented for the proposed analysis method and compared to analyses found in previous literature.
