 Abstract
The paper presents a method to calculate displacement and stresses that appear in thin wall U-profile sections poles. Displacements of the section is considered to be restrained, due to links and torsion momentum variation along the pole, which produces both torsion and bending alongside the pole. The results obtained using this method differs from those using the elementary torsion stress theory that considers section movement to be free. When projecting this pole types the stress verification must be done using this calculation method.

 Rezumat
În lucrare este prezentată o metodă exactă pentru determinarea stării de tensiuni în secţiunea unei bare cu pereţi subţiri de forma unui profil U, considerând deplanările secţiunilor împiedicate, supusă la torsiune. Ca urmare a modului cum sunt considerate deplanările, în secţiunea barei apar şi tensiuni normale, pe lângă cele tangenţiale, astfel încât pentru verificare este nevoie să se aplice o teorie de rezistenţă.
