| Abstract: | The problem existing in calculating the ultimate flexural strength of the preflex composite beam is discussed in this paper, a more accurate method for calculating the ultimate flexural strength with the elasto-plastic effect is developed. The formula has a clear physical concept and is quite convenient, and its results have a better approach to the test values. |
