Js. Kuang et Ct. Morley, A PLASTICITY MODEL FOR PUNCHING SHEAR OF LATERALLY RESTRAINED SLABS WITH COMPRESSIVE MEMBRANE ACTION, International journal of mechanical sciences, 35(5), 1993, pp. 371-385
A plastic theoretical model is presented for the punching shear failur
e of laterally restrained concrete slabs, in which a parabolic Mohr fa
ilure criterion for concrete is adopted. The proposed method allows fo
r the effect of compressive membrane action and a membrane-modified fl
exural theory of elasto-plasticity is used to calculate the compressiv
e membrane forces. The predictions by the proposed analysis show good
agreement with a wide range of experimental test results.
