Abstract
The responses of reinforced concrete beams subject to low velocity impact loading are simulated using orthotropic constitutive model incorporated with Smoothed Particle Hydrodynamics (SPH) method. The tensile failure of the beam is using the orthotropic constitutive equation during the softening phase on tension region, where the three principle strain components for tension (positive value) and compression (negative value) are used independently. In order to validate the proposed model, two impact cases were analyzed. The first case is simulation of simply supported beam without shear rebar using SPH and FEM. The second case is involving the comparisons of impact case of RC beam using proposed model with existing experimental tests. By adopting orthotropic constitutive equation and tensile softening algorithm defined by damage parameter, flexural cracks and shear failure can be analyzed by tracing the local stress condition.
