| Abstract: | According to the stress mechanics of the steel-bonded reinforced beams which are strengthened in compressive zone,the formulas of defining the ultimate flexural capacity of the failure modes,the critical flexural capacity and the critical strengthened height of the steel plate are suggested.The results are compared with the test results of steel-slab-bonded reinforced beams.Finally the deviation is analyzed and the modified method is presented. |
