Abstract

The article focuses on the application of the Coupled Damage-Plasticity Microplane (CDPM) material model equipped with ANSYS software in simulating the nonlinear behavior of concrete materials. The nonlinear behavior of the reinforced concrete (RC) slab which was designed according to ACI 318-08 standard under monotonically increasing load is analyzed based on The Finite Element Method. The three-dimensional finite element model of the three-point bending test of the RC slab was built in ANSYS/Workbench software (ANSYS Student 2020). The solid eighth-node CPT215 elements are employed in the simulation for concrete material whereas the embedded REINF264 elements are used to simulate the rebars. A crucial part of this paper is a determination of the suitable input parameters of the CDPM material model (15 parameters) for the considered flexural RC slab. The numerical results of the relationship between the applied load and the displacement at the mid-span of the RC slab are presented and compared with the experimental results of the previous study.
