| Abstract: | Through tests of rectangular section reinforced concrete beams,the bending resistance capacity of reinforced concrete beams strengthened with carbon fiber reinforced plastics(CFRP) and stick steel are studied experimentally,The main factors that influence the bending resistance capacity of the strengthened beams are analyzed.The calculation results are in good agreement with test data.Moreover the feasible design indenes of the two kinds of strengthen methods are obtained. |

| Keywords: | strengthened by stick steel concrete beams bending bearing capacity |
