The PARC_CL 2.0 crack model is an evolution of the previous PARC versions and, with respect to them, it allows to take into account plastic and irreversible deformations. For this reason, it seems to be suitable for modelling the hysteretic cycles of both concrete and steel and to reproduce the cyclic response of structural R members. Moreover, within the PARC_CL 2.0 crack model, is implemented a formulation able to account for stiffness proportional damping in dynamic analyses. The shear walls, tested by means of PSD test, at the ELSA laboratory have been used to validate the proposed PARC_CL 2.0 crack model; the shear walls have been modeled using multi-layered shell elements and NLFEA have been carried out considering several loading condition (static pushover, cyclic and dynamic). The static pushover analyses are used to evaluate the sensitivity of results to mesh discretization; several analyses have been carried out adopting different element size in order to see the effect on the structural response.Moreover, cyclic and dynamic analyses are used to evaluate the capability of PARC_CL 2.0 crack model to reproduce the hysteretic response of such RC structural members.
