Abstract
An analytical model for lateral strength and deflection of cracked unreinforced masonry walls is developed. Post cracked behavior is considered by neglecting shear transfer across cracked masonry. Based on shear and normal stress distributions derived with the model, possible failure modes are examined. Effects of cracking are considered by modifying conventional expressions for lateral deflection 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. Based on a series of computations using the model, tables are generated for estimating lateral strength in terms of different material parameters, amounts of vertical compressive stress, and wall length-to-height aspect ratios.
