| Abstract: | Esta tese consiste na análise de nós de hastes de paredes delgadas quando submetidas a bimomentos e à influência de enrijecedores. Vários tipos de enrijecedores foram estudados, através de um programa de elementos finitos para cascas, o qual considera isoladamente os esforços de estado plano de tensões e flexão de placas. Dois exemplos foram estudados. O primeiro - grelha - são testados três tipos de rigidezes adicionais. O segundo - pórtico plano - duas rigidezes adicionais são testadas. Os resultados são descritos em tabelas e esboçados em gráficos que possibilitam conclusões sobre a análise realizada. |
| Abstract: | 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. |
