In this paper theproblemof calculation the generalized sectorial coordinates foran arbitrary thin-walledsection has been considered. Thin-walled section can consist of several closed (connected and/or disconnected) contours as well as of non-closed parts. Formulated taskhas been solved in terms of distribution factors usingmathematicalapparatusofthe graphtheoryandthe settheory. Adetail numerical algorithm devoted to software implementation in computer-aided systems for thin-walledbar structures has beene laborated and presented.
