This paper deals with the role of the spandlers in the seismic behaviour of the masonry building. Particularly the seismic performance of masonry walls in their own plane have been analyzed by mean of non-linear static analyses performed on schemes of equivalent frames. Different geometrical and structural configurations of the spandlers have been considered and the corresponding capacities in coupling the piers have been deepen too. Both beams and columns have been modeled considering lumped plasticity at the ends of the elements. The results obtained confirmed the very strategic role of the spandlers in the seismic capacity of the masonry building
