This thesis consists in the analysis of joints of thin walled beams when submited by bimoments and under the influence of additional stiffnesses. Several types of additional stiffnesses were studied through the program of finite elements applied to shells; it considers disconnected efforts of plane state stress and bending of plates. Two examples were analised. The first one - grid - was examined by three types of additional stiffness. The seoond - plane frame - two additional stiffnesses are examined. The results are presented in tables and graphs what enable conclusions about the analysis done.
