Torsion of bars with uniform cross-sections is studied by many researchers, and the problem is well known as Saint-Venant torsional one. However, a few researchers have investigated as three dimensional problem. In this paper, the author conducted numerical analysis of torsional problem bythe finite element method using software called LUSAS. Numercal examples are shown for typical three kinds of cross-sections. Tortional moment subjected to concentrated loads at the end of the bars is compared with analytical solution. And the validity of Saint-Venant problem is proved.
