A BEM formulation is proposed improving the solution technique presented in a previous recent paper. Different bond stress-slip local nonlinear laws are considered in order to verify the reliability of the approach proposed, and the results of several applications are compared with those obtained by other authors using FEM models or deduced by experimental tests. From a computational point of view, the procedure proposed proves to be advantageous, because it involves a reduced number of unknowns and of
