Concrete and Reinforced Concrete Strength under Action of Shear, Crushing and Punching Shear
IOP Conference Series: Materials Science and Engineering
Sufficiently general technique for calculating strength based on mathematical concrete plasticity theory apparatus, variational method with virtual velocities principle application, discontinuous solutions, and ultimate load magnitude upper estimate is proposed. Ultimate state simultaneous existence condition on failure entire surface is criterion for plasticity theory applicability. Strength problems of flat and spatial concrete and reinforced concrete elements are solved under crushing, sheardoi:10.1088/1757-899x/463/2/022026 fatcat:dxmesd52qbdnzk2dxkd563fhgi
