In a previous paper a formulation for the analysis of Kirchhoff plates with subregions with different thicknesses by the boundary element method with the aim of analysing building floors was presented. In this formulation the floor can be analysed as only one structural element and neither compatibility nor equilibrium relationships at the interfaces are required in order to assemble the final system of equations. In this paper the boundary integral equations of curvatures of points located at the zone's interfaces are deduced in a very easy way allowing to get the bending moments at these points easily. The formulation was tested for zoned plates and the results were compared with those obtained with finite element method with refined meshes and the results demonstrate very good agreement.
