Seismic Performance of Heritage Clay Brick and Lime Mortar Masonry Structures

This paper summarizes recent investigations into the structural and material response of ambient-dry wet clay-brick lime-mortar masonry elements, with focus on those used in heritage structures Historic Cairo. In addition to cyclic tests large-scale walls subjected lateral displacement compressive gravity loads, studies included complementary small scale panels specimens. It is shown that moisture can have a notable effect main properties, including shear compression strengths, brick-mortar interaction parameters, elastic moduli. The extent effects function governing behaviour characteristics as well between precompression stresses lead loss more than third stiffness strength reduction ductility. Simple cost-effective strengthening techniques, using textile-reinforced mortars, for enhancing performance low-strength element, are also considered this study. effectiveness approach illustrated quantified through additional small-scale wall simple analytical assessment methods be reliably adapted predicting specimens, terms stiffness, overall load-deformation behaviour.
