title: Data from: A heretical point of view in masonry structures dynamics

description: Protection from static and dynamic actions is an urgent matter for masonry
 buildings, which constitute the majority of the world’s architectural
 heritage. For this reason, the search for best strategies to analyse the
 mechanical responses of such structures under both dead and seismic loads
 has been at the center of a vivid debate within the scientific community
 for decades. Although many different approaches and computational methods
 have been proposed in the literature over the years, most of them makes
 reference to no-tension materials, starting from the pioneering work by
 Heyman in the framework of Limit Analysis. However, implementing the
 hypothesis of masonry walls made by rigid blocks interacting through
 no-tension interfaces often leads to inconsistent results due to possible
 interpenetrating elements. In explicit dynamic models simulating
 earthquakes, the occurrence of undesired blocks' overlapping forces
 algorithms to continuously check the compatibility to eventually stop and
 restart the analysis with somehow arbitrary initial conditions. By
 introducing well-established hyperelastic and friction laws at bricks’
 interfaces to recover physical consistency, we propose a heretical
 strategy that overcomes some difficulties of above-mentioned approaches,
 drastically reducing computational costs, a-priori avoiding any
 interpenetrations and allowing reliable outcomes under various dynamic
 boundary conditions.

 [https://doi.org/10.5061/dryad.bvq83bkjb](https://doi.org/10.5061/dryad.bvq83bkjb) The Dataset is a compressed file, including the Mathematica notebook, named as "Code.nb" and .dat and .txt files. In detail, the .dat files contain the set of mechanical and geometric parameters employed, while the .txt files provide the displacements and velocities histories resulting from the calculations done for the corresponding set of parameters.  ## Description of the data and file structure The Mathematica notebook reads the Data of the problem from the .dat files and reconstructs the geometry of the masonry panel. For the users' convenience, by the way of example, two case studies resulting from the calculations of the explicit dynamics of the masonry panels selected are included in the .zip archive and the displacement, velocity and base shear histories can be plotted in the Mathematica environment. Starting from arbitrary sets of parameters, one can calculate and reproduce other numerical case-studies, following the computational workflow provided in the paper published in the Royal Society Open Science Journal. We emphasize that for reducing computational burdens, it could be possible to export the ordinary differential equations from Mathematica to the Matlab environment where they can be solved. The numerical results are then again reported in Mathematica-readable form through the exchange protocol Mathematica-Matlab and can be displayed. To hybridize Mathematica and Matlab the open source plugins have been utilized: ToMatlab ([https://library.wolfram.com/infocenter/MathSource/577/](https://library.wolfram.com/infocenter/MathSource/577/)) and Matlink ([https://matlink.org/](https://matlink.org/)).For further details, refer to the paper.
