Based on the developed shear and normal stress distributions with cracking, the possible failure modes in an unreinforced masonry wall are examined. Some failure criteria are directly related to the results of nondestructive measurements. To consider effects of cracking, the conventional expression for lateral deflection is modified with shear and flexural deformation amplifying factors. The feasibility of the evaluation procedure is verified through correlation with the results of experimental work done by others.
