Shape memory alloy crossbracing of brick masonry walls: cyclic test of a large scale model and numerical analysis
An innovative seismic protection system for ancient masonry structures is presented. A cross bracing system based on Shape Memory Alloy (SMA) devices, that provides energy dissipating capacity and stability improvement, was developed by F.I.P. Industriale. The main results from the preliminary mechanical characterization of the NiTi wires adopted in the devices are presented. In order to implement the new protection system, the behaviour of large scale masonry panels is experimentally investigated at the European Laboratory for Structural Assessment (ELSA) as part of the on-going research project ISTECH. Finite Elements Method (FEM) analyses of the walls are then with the experimental evidences.
