Non-linear continuous model for three leaf masonry walls

Three-leaf brick masonry wall is a typical technique in historical buildings. Sensitivity of three-leaf brick masonry wall to core mechanical characteristics and interface between layers is studied by reference to an experimental campaign. Experimental activities were performed on three-leaf masonry panel under compressive loads and is used to identify mechanical characteristic of three-leaf masonry wall and calibrate a 2D plain strain model (without and with interfaces between layers) for cross section of panel. A parametric analysis on inner core and interface between layers mechanical characteristic sensitivity is proposed. Numerical modeling results are presented and discussed in comparison with experimental data.
