heal.abstract	Three phenomenological constitutive models are presented for the response of reinforced concrete elements. The first is a simple uniaxial stress-strain model, based on the Mohr-Coulomb failure criterion, developed by Gerolymos et al (2014). This model possesses considerable flexibility to reproduce the macroscopic behavior of reinforced concrete circular sections. The second is a mathematically simple model, also formulated within the framework of classical elastoplasticity. Concrete material is described by Mohr-Coulomb failure criterion and it is combined with elastoplastic reinforcement elements. The third approach is a combination of elastoplastic reinforcement elements and an advanced model for concrete material, that employs the Mohr-Coulomb failure criterion for deviatoric loading and Rankine for tension. Due to its formulation it accounts for strain hardening and softening. Nonlinear three-dimensional analysis is used to conduct a thorough investigation on the performance of the aforementioned models utilizing Plaxis 3D Finite Element Software. The models are first calibrated and then compared and validated against results from computer codes. After validation, the proposed models are implemented in pile-soil interaction cases and their performance is evaluated utilizing Broms theory (1964) of ultimate pile lateral capacity. Nonlinear behavior of the soil and the pile is considered, and pile-soil response is investigated through a detailed parametric study.	en
