| Abstract: | Finite element simulative analysis by ANSYS software are conducted for the concrete beams strengthened with the besides adhibit the fiber or the exterior glues the steel.The concept of the partial separation model is introduced with the reinforced concrete model element and it verifies that the besides adhibit the fiber strengthen or the exterior glues the steel strengthen can effectively improve the whole capability of the reinforced concrete beam,and that the analytic results of the part separate model and the whole separate model are almost close. |
