Abstract

The paper presents different modelling approaches available within the finite element code Mady and their influence in the analysis of the seismic behaviour of masonry towers. The considered models, developed on purpose for masonry structures in the last decade, have different levels of complexity and different constitutive hypotheses. In the framework of the continuous homogeneous models, they range from the simplest no-tension material to more refined models, accounting for bounded tensile and shear strengths with damage process and plasticity in compression. Moreover, a beam model as well as plane, shell and brick elements are available. The investigation is aimed to highlight some of the main differences in the seismic response of masonry towers that can emerge by using different models provided by the code. Particularly, the obtained results are compared and discussed mainly focusing on earthquake resistance, failure modes, type and distribution of the predicted structural damage.
