Abstract
This paper presents the development of an updated version of PARC_CL 2.0 crack model implemented in Abaqus Code using subroutine UMAT.for. The PARC_CL 2.0 model is a fixed cracked model for the response prediction of reinforced concrete members. More refined material constitutive relationships were incorporated in the formulation of the model to take into account plastic deformations. Finally, to validate the model, reinforced concrete (RC) panels subjected to cyclic loads, available in literature, are modeled and compared with experimental observations. The PARC_CL 2.0 model was able to capture, with reasonable accuracy, the overall behaviour including cyclic shear stress vs. shear strain behaviour, shear stiffness, cyclic stiffness degradation, energy dissipation during the cycles and pinching effect.
