An analytical investigation of the behaviour of concrete under concentrations of load

摘要: Nonlinear finite element techniques based on either a linear description of stress-strain relationships concrete and the failure criterion described in reference [3] or nonlinear model behaviour references [2] [3], have been used to analyse plain structural forms subjected wide range boundary conditions. The analysis use has found yield most realistic predictions strutural response which correlate very closely with published experimental data. In addition, it that post-ultimate strength under compressive states stress no effect overall for cases investigated.
