Data set Contents
The data set consists of a compressed folder, named HOLAHERIS_OptimisedMultiLevel-data.zip, containing:
•	10 .csv files with data related to base shear-displacement curves obtained with block-based models (micro) and with the proposed optimized multi-level models (macro) on five structural benchmarks (“Ferris”, “Façade”, “GoodQuality”, “BadQuality”, “Arch”). This data allows future comparisons. In each .csv file, the first column collects the displacement data in m, while the second column collects the base shear data in N.
o	OptimisedMultiLevel_FerrisMacro.csv
OptimisedMultiLevel_FerrisMicro.csv
These files contain base shear-displacement curves, obtained with a block-based model (micro) and with the proposed optimized multi-level model (macro). The data are presented in Figure 11 of the related paper (see “Notes” section).
o	OptimisedMultiLevel_FacadeMacro.csv
OptimisedMultiLevel_FacadeMicro.csv
These files contain base shear-displacement curves, obtained with a block-based model (micro) and with the proposed optimized multi-level model (macro). The data are presented in Figure 14 of the related paper (see “Notes” section).
o	OptimisedMultiLevel_GoodQualityMacro.csv
OptimisedMultiLevel_GoodQualityMicro.csv
OptimisedMultiLevel_BadQualityMacro.csv
OptimisedMultiLevel_BadQualityMicro.csv
These files contain base shear-displacement curves, obtained with block-based models (micro) and with the proposed optimized multi-level models (macro). The data are presented in Figure 15 of the related paper (see “Notes” section).
o	OptimisedMultiLevel_ArchMacro.csv
OptimisedMultiLevel_ArchMicro.csv
These files contain base shear-displacement curves, obtained with a block-based model (micro) and with the proposed optimized multi-level model (macro). The data are presented in Figure 18 of the related paper (see “Notes” section).
•	10 .inp files which are Abaqus input files containing the finite element models and the loading conditions for different benchmarks. These files can be opened as standard text files. Accordingly, the block assembly, the nodes coordinate matrix and the element connectivity matrix can be extracted from each .inp file.

Abstract
This dataset, developed in the framework of the H2020 HOLAHERIS project, contains results data related to an optimised multi-level method to account for the actual masonry pattern in the pushover analysis of historic masonry structures. The method uses (i) a rigid block-based limit analysis to identify realistic failure mechanisms accounting for the actual masonry pattern. Then, (ii) macro-blocks outlining the failure mechanism are identified based on a heuristic search. Finally, (iii) macro-blocks are modelled as homogeneous material interacting via cohesive-frictional interfaces in a finite element environment where base shear-displacement curves can be extracted by means of pushover analyses. Base shear-displacement curves obtained with this optimised multi-level method on five structural benchmarks, as well as the finite element models, are collected herein to provide data for future comparisons.
File specifics
The .csv files were created with the following specifics:
