== Abstract ==

As plataformas offshore de concreto, por estarem sujeitas a diversas combinaçoes de carregamento e, portanto, exigirem uma análise mais genérica possível,podem ser analisadas utilizando os conceitos desenvolvidos para elementos de cascas, desde que a verificaçao da capacidade resistente em seçoes particulares para as forças cisalhantes seja feita. Neste trabalho o dimensionamento dos elementos de casca foi feito a partir da teoria de cascas de tres camadas. Os elementos estao submetidos a solicitaçoes combinadas de membrana e placa, com um total de oito componentes de forças internas, sendo tres de membrana, tres de momentos fletores e duas de esforços cisalhantes. O dimensionamento proposto, utilizando o processo iterativo desenvolvido por Lourenço & Figueiras (1993) a partir das equaçoes de equilibrio de Gupta (1986), é comparado com resultados experimentais obtidos da literatura por meio de uma análise feita com o programa DIANA. Summary The concrete ffshore platforms, which are subjected a several loading combinations and, thus, requires an analysis more generic possible, can be designed using the concepts adopted to shell elements, but the resistance must be verify in particular cross- sections to shear forces. This work about design of shell elements will be make using the three-layer shell theory. The elements are subject to combined loading of membrane and plate, totalizing eight components of internal forces, which are three membrane forces, three moments (two out-of-plane bending moments and one in-plane,or torsion, moment) and two shear forces. The design method adopted, utilizing the iterative process proposed by Lourenço & Figueiras (1993) obtained from equations of equilibrium developed by Gupta (1896), will be compared to results of experimentally tested shell elements found in the literature using the program DIANA.
