| Abstract: | The failure types are described according to the test beams strengthened with prestressed CFRP sheets. Measures of decrease prestress loss are provided. The simple and convenient formulas for flexural strength are proposed. The rusuhs from the fomulas generally agree with those from the experiment. |
