RESUMO

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.
