Since the expression of bending-torsion was deduced by H. Wagner in 1929. many studies have been done. But, most of these studies are those of torsional buckling for compression members, and tests for bending members suffered with bending-torsion are scarcely done. Then, we have done this kind of tests for V shaped cross-section beams and compared the results of these tests with the solution of Wagner's equation. As the conclusion, it has been known that the solution of Wagner's equation agrees with the actual state of bending-tortion. And to remove the complexity in solving the Wagner's equation we have presented a method in which simple equations and coefficients shown in graphs are used.
