Yield‐Line Analysis of Slabs‐on‐Grade

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 vs. a load distribution parameter are presented for the proposed analysis method and compared to analyses found in previous literature.
