Abstract in Portuguese
Este trabalho apresenta o estudo de uma formulação do método dos elementos de contorno para a análise da interação placa-viga de pavimentos de edifícios. Para compatibilizar adequadamente as vigas e a placa, é utilizada uma formulação alternativa do método dos elementos de contorno para placas delgadas em que, a viga é modelada por equações diferenciais ordinárias e, a compatibilidade entre a placa e a viga é feita por meio dos deslocamentos e forças de ligação nos nós dos elementos. Após a imposição das condições de contorno e resolução final do sistema de equações, são obtidos os esforços nas vigas e deslocamentos na placa, que por fim são confrontados com outras formulações. Exemplos foram analisados demonstrando uma ótima concordância com os exemplos obtidos por outras formulações.

Abstract in English
This work presents a formulation of the boundary element method for the analysis of plate-beam interaction in buildings floors. In order to properly match the beams and plate is used an alternative formulation of the boundary element method for thin plates, in which the beam is modeled by ordinary differential equations and the compatibility between plate and beam is done by the displacements and forces of connection in the nodes of the elements. After applying boundary conditions and final resolution of the system of equations, efforts are obtained in beams and plate displacements, that are confronted with other formulations. Samples were analyzed showing excellent results compared with those obtained by other formulations.
