The structures are initially studied alone and afterwards compatibilized into coupled structures, that is, assemblages, including tanks and pressure vessels. Examples are analysed and, in order to prove accuracy, the results were compared with those furnished by the analytical solutions / O presente trabalho aborda a an?lise linear de estruturas de superf?cie axissim?tricas atrav?s do desenvolvimento e implementa??o de um c?digo computacional baseado no M?todo dos Elementos Finitos. Inicialmente, as estruturas s?o estudadas de maneira isolada e, em seguida, compatibilizadas de modo a formar estruturas acopladas, como reservat?rios e vasos de press?o. Exemplos de aplica??o, com diferentes tipos de solicita??o e condi??es de vincula??o, s?o apresentados e os resultados obtidos pelo c?digo desenvolvido s?o comparados a valores anal?ticos
