Abstract: The collapse load of a reinforced concrete square spread footing under column load is derived by using the theory of plasticity. Several upper bound solutions corresponding to different yield line patterns are obtained. ...

Abstract: A theoretical solution for the punching shear strength of a concrete slab is presented. The problem is treated as a three‐dimensional axisymmetrical one, the material being assumed to be rigid‐plastic. A failure criterion ...

Abstract: Formulas to predict the ultimate shear strength of reinforced concrete deep beams are proposed. The derived equations are based on limit analysis theorems and associated flow rule. The lowest upper‐bound solution is achieved ...
