The proposed model considers major characteristics of mass concrete under three dimensional loading conditions. These characteristics are pre-softening behavior, softening initiation criteria, fracture energy conservation and strain rate effect. After verification of the proposed model by some available numerical tests, dynamic analysis of the Morrow Point concrete arch dam under the three components of the Taft earthquake scaled to 1.0g is carried out. In the present analysis, complete fluid-structure interaction is considered accounting for fluid compressibility and absorptive reservoir boundary condition appropriately. The coupled equation resulting from dam-reservoir interaction was solved using staggered method. The deduced results show that crack pattern has good agreement with the contour of maximum principal stresses. The proposed algorithm also gives reliable solution even in large time steps.
