Data from the parametric analysis of multi-ring masonry arches using a limit analysis approach for the span of 3m (Q6708117)

The dataset is produced by running a series of 360 simulations 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 120 simulations achieved for the multi-ring masonry arches for span of 3m with different level of parameters considered, namely size of blocks, span of the arch, ring number, interlocking coefficient and the friction angle.In order to simplify references to figures an acronym system is used and it follows a sequence of size_span_ring_interlock_friction. Size takes attributes as S-small and B-big while span takes number attributes based on the span like S3, S5, S7 for spans of 3, 5and 7meters, respectively. Ring number similarly is based on the number of rings as R2, R3, R4 and R5and interlock takes the following attributes, I00, I15, I35and I50for the interlocking percentage considered such that 00-stacked, 15%, 35% and 50%, respectively. Finally friction takes attributes following the angle of friction such as F25low level, F30medium level, and F35high level. The acronym used for the equivalent one-ring arches is used as simply EQ. For example, the acronym S_S7_R4_I35_F30 refers to the arch with small blocks, span of 7meters, consisting of 4rings and by blocks interlocked at 35%with a joint friction of 30o. This databasecontains a *.txt, a *.vtk and a *.png file. In the .txt file the elapsedtime and the collapse multiplier of each simulation can be found. The .vtk file contains all the geometry and displacement values of every masonry panel. Finally, the .png file presents the collapse mechanism obtained.
