Numerical Methods for Slender Masonry Structures: A Comparative Study

This paper is devoted to comparing two numerical approaches for modelling the dynamic behaviourofmasonry structures. Itpresents theconstitutive equationofmasonrylike materials with bounded compressive strength and addresses the dynamic problem for both three-dimensional bodies and one-dimensional structures. The numerical methods implemented in the codes NOSA-ITACA and MADY, respectively for threeand one-dimensional structures, are outlined. With the aim of comparing the two numerical procedures, a masonry tower with rectangular cross-section is analised. The structure is subjected to its own weight and an accelerogram recorded during a real earthquake. This comparison has emphasised the importance of employing accurate constitutive models when analysing masonry structures.
