Experimental Database on the In‑Plane Behaviour of Calcium Silicate Masonry Walls with Thin‑Layer Mortar Considering Multiple Geometries, Boundary Conditions, and Loading Scenarios

This database presents experimental results obtained from ten full-scale calcium silicate block masonry walls tested under in-plane quasi-static loading. The test programme includes specimens with and without openings, different aspect ratios, and two boundary support conditions: cantilever (CL) and double-clamped (FF). The walls were subjected to repetitive, cyclic, and near-collapse loading histories under controlled vertical pre-compression. The resulting open benchmark database is intended to support the calibration, validation, and comparison of numerical models by providing specimen geometry, loading and boundary conditions, global hysteretic response, and DIC-based damage information in a consistent and reusable format.
