The Masonry Microstructure Database (MMS) platform is the first open-access repository of 3D microstructures of stone masonry walls. Masonry microstructure, defined by the geometry, size, shape, and spatial arrangement of individual stone units, significantly influences structural performance. The database currently includes 36 walls covering major masonry typologies. Twelve walls are real, built and scanned in laboratories, and twenty-four are virtual, generated using digital masonry microstructure generators from the literature. Each wall is characterized using the Geometric Masonry Quality Index (GMQI), which is based on the well-known Masonry Quality Index (MQI) but considers only geometric parameters.
ENAC-IT4R developed the platform with support from an ORD Explore grant, while the EESD laboratory gathered the database, generated the computed metadata, and provided the calculations tools.
