Abstract
The objectives of this study are to evaluate the variables that affect the shear behavior of unreinforced masonry (URM) walls and to propose the equation of the rocking and toe crushing strength of URM walls by regression analysis using the test data including the previous research. The main variables are the axial stress, the aspect ratio and the thickness of URM walls. The test results show that the specimens are governed by rocking and toe crushing failure modes. The relationship of the shear strength is proportionate to the square root of the vertical axial stress, and the relationship of the shear stress and aspect ratio is linearly proportional. Shear strength and cross sectional area are not proportional. For the URM walls tested, the proposed rocking and toe crushing strength/actual strength ratio of 0.95, and coefficient of correlation R of 0.9889 are more appropriate than the FEMA 306 rocking and toe crushing strength formulas.
