Plastic Model for Concrete in Plane Stress State. II: Numerical Validation
Publication: Journal of Engineering Mechanics
Volume 124, Issue 6
Abstract
A constitutive model for plain concrete proposed in Part I of this paper is comprehensively verified by a comparison of the model prediction obtained numerically with available experimental data for the plane stress state. At first, calibration of some model parameters is briefly discussed. Next, the model validation is made at the material point level for monotonic proportional load paths in the stress space covering all possible stress combinations, i.e., the compression-compression, compression-tension, and tension-tension regions. In the following, the postcritical behavior in uniaxial compression and tension is thoroughly studied. Next, the model prediction for cycling loadings is compared with experimental data, mostly for uniaxial compression and tension. Finally, two examples of structural computations of reinforced concrete (RC) deep beams for model implementation into an FEM code are presented. A good agreement with experimental data is found at the material point level. Also, the FEM computations render satisfactorily the actual behavior of RC deep beams.
