This is a thesis, divided in six Chapters, that studies torsion in thin walled beams. In Chapter I, the necessary concepts to the development of the thesis are exposed: Bimoment and warpihg torsion, sectorial properties of a section. In Chapter II, an analytical study of bimoment is presented: the warping of a section, normal and shear stresses, the bimoment differential equation. Chapter III shows the resolution of a thin walled continuous beam through the usual hyperstatics methods: force method and displacement method. Chapter IV studies the construction of bimoment influence lines of continuous beams subjected to torsional moment. In Chapter V there is an example of numerical determination of tensions in thin walled beams. Chapter VI relates the conclusions found in this study. In all Chapters, various examples were developed in order to clarify the exposed subjects.
