The paper presents an analytical discussion of the free transverse vibrations of masonry beam-columns, focusing on the role of the material's inability to sustain traction in modifying the dynamic behavior of such structures. In particular, for periodical oscillations, an analytical method is presented for obtaining an explicit relation between the fundamental frequency of the beam and the amplitude of displacements.
