Simplified analytical expressions for the compressive strength and elastic properties of solid brick masonries

One of the main difficulties when working with heritage structures is the difficulty of assessing the compressive strength of masonry and the other mechanical properties such as the elastic orthotropic properties. In addition, actual masonry codes are focused on modern fabrics which normally include...
