| Abstract: | Following the analysis of experimental data of 370 prestressed concrete and partially pressrested concrete beams, the author suggests calculation formulas of the anti-cracking shearing strength for inclined section of beams, which are simple and easy to use. The formulas include the main factors, and in good agreement with the experimental data. This paper also analyzes some problems in current calculation methods of the principal tensile stress. |
