Yield-line theory for reinforced concrete slabs at moderately large deflexions
Conventional yield-line theory for reinforced concrete slabs is extended to allow for membrane effects and moderately large deflections, by isolating those membrane displacement rates of rigid slab portions which do not affect yield-line positions, and developing method of choosing these rates so that load estimate from work-rate equation is stationary; for slab with assumed pattern of yield lines, relationship between load-carrying capacity and deflection can then be obtained; number of examples are worked, with different shapes of slab and boundary conditions.
