A non-intrusive seismic retrofitting technique for masonry infills based on bed-joint sliding

In recent years, several seismic retrofitting projects of existing buildings have been involving additional measures to improve their energy efficiency, thanks to new regulations aiming at optimizing the buildings overall performance. Significant improvement is usually obtained through radical measures aiming at strengthening the infill panels, typically vulnerable to both out-of-plane overturning and in-plane cracking, and at enhancing their thermal insulation. Measures not disrupting the internal activities are generally favored.
