000019221 520__ $$2eng$$aA multi-fiber beam finite element based on the Timoshenko theory is proposed to simulate failure of reinforced concrete structural elements subjected to static or seismic loadings. The elements section can be of arbitrary shape and each fiber has a local constitutive law representing a specific material. The embedded discontinuity concept is adopted to enrich the fiber displacement field in order to describe crack openings and the development of plastic hinges. The material behavior at the discontinuity is characterized by a linear cohesive law linking the axial stress and the displacement jump, which permits to capture the released fracture energy. The variational formulation is presented in the context of the incompatible modes method followed by the corresponding computational procedure. Finally, two numerical applications are given to illustrate the performance of the proposed multi-fiber Timoshenko beam finite element.
