The different formulas for the calculation of internal forces of section are deduced according to the different development stages of strain and a flow diagram for the calculation is established. With the program based on the diagram, the internal forces and some relevant parameters of the strengthened beams are calculated and the main factors which affect the ultimate bearing capacity of the beams are discussed.
