Summary:Studying the effects of the earthquakes’ vertical component on the dynamic response of masonry buildings is still an open issue. This subject is investigated using a simplified masonry-like beam model with a generalized stress–strain relationship. The nonlinear dynamic equations that couple the transverse and axial oscillations of the beam are solved numerically. Some examples are presented and discussed, focusing on the structural typology of masonry towers and the recent earthquakes that threatened the North-Central Apennines in Italy. •Effects of the seismic vertical component on the dynamic response of masonry towers.•Nonlinear coupling between axial and transverse oscillations of masonry beam elements.•Some examples are discussed, inspired by real case studies and earthquake records.
