This work consists on the application of the Boundary Element Method for the analysis of homogeneous, isotropic and linearly elastic plates, when the refined Reissner's theory is used. First, a summary of Reissner's model for the bending of plates is shown. Then, the Boundary Element Method is developed for this formulation, with the basic integral equations being deduced through two alternative procedures. The fundamental solution is also presented and it is shown how the method can be applied to infinite plates. The procedures used in the numerical implementation of this formulation are described and the corresponding program structure is presented together with its user's manual. At the end, some numerical examples are presented and the results are compared to analytical solutions.
