Data from the validation of experimental large scale tilting table results with the in-house ALMA limit analysis code for the case of walls with different texture and aspect ratio

The dataset is produced by running a series of 816 simulations (204 each for ENG, RUN, SRU and STK) using the in-house code ALMA (Analisi Limite Murature Attritive) that implements the upper bound approach of limit analysis to detect the collapse multiplier and mechanism for masonry structures. This set of data contains the results of 816 simulations achieved for the limit analysis of masonry walls with different aspect ratios of the wall and various internal textures. Wall aspect ratios differ from squat walls (denoted with 05), square walls (denoted with 10) and slender walls (denoted with 15), for ratios 2:1, 1:1 and 1:2, respectively.  Regarding levels of texure, four have been used, namely STK, ENG, RUN and SRU. STK is the stacked bond, ENG is for an English bond, RUN is for the running bond with larger bricks compared to the SRU ruinning bond with smaller bricks.

Various imperfections have been implemented in the geometry for the simulations which are introduced based on some parameters. WallsPiers have horizontal reductions denoted with the greek letter xi (in files denoted with KS) and vertical reductions denoted with the greek letter eta (in files denoted with ET). Finally, four different levels of friction angle are considered (30o, 33o, 36o and 39o) that in the files are denoted with F. Another imperfection was introduced with the inclusion of a horizontal gap for the vertical joints denoted with VD, where VD-00 means no gap and VD-99 means there is a gap. The aspect ratio of walls are differentiated with RAT. Therefore, the files are separated in folders differing from the type of wall texture (ENG, RUN, SRU and STK) and each file is based on an acronym system formed for example:

"ENG_RAT-05_VD-99_KS-15_ET-05_F36" --> ENG - the nomination of texture; RAT-05 - the aspect ratio of the wall as 05; VD-99 - the switch between gap and no gap, in this case 99 means gap; KS-15 - is the horizontal reduction for a value of 15 mm; ET-05 - is the vertical reduction for a value of 50 mm; F36 - is the friction angle with a value of 36o. For KS and ET with values of 0, a perfect geometry is intended.

Each folder of this database contains  *.dxf, *.txt, .vtk, *.xml and *.png files. In the .dxf files are stored the geometries of the structures under study. In the .txt file the elapsed time and the collapse multiplier of each simulation can be found. The .vtk file contains all the geometry and displacement values of every masonry panel. The .xml files have the input files required for the ALMA code. Finally, the .png file presents the collapse mechanism obtained.
