The needs for analytical tools to support experiments and design processes led to a computer program for the Inelastic Damage Analysis of Reinforced Concrete Frame-Shear Wall Structures, IDARC. The program, based on original developments of constitutive models and structural modeling, performs an equivalent static and dynamic response analysis of R/C structures under earthquake excitations. The equivalent static analysis determines the component properties including the identification of the inelastic behavior and failure mode under monotonic loads, as well as the determination of the natural period of the structure. The step-by-step inelastic dynamic response analysis is performed using a 'three-parameter' hysteretic model for reinforced concrete elements which permit modeling of shear and flexure differently.
