Abstract

The aim of this paper is to study the compressive strength and behavior of interlocking block masonry under eccentric loading. Interlocking block masonry prisms were tested under eccentric loading with the ratios of eccentric distance to sectional length e/h = 0, 0.18, 0.27, 0.36 and 0.45. The test results show that as the eccentric distance increases the compressive strength decreases. The compressive strength correlations of interlocking block masonry (f_m¢) under eccentric loading found in this study were (f_m¢)_e/h=0.18 = 0.815(f_m¢)_e/h=0,  (f_m¢)_e/h=0.27 = 0.632(f_m¢)_e/h=0, (f_m¢)_e/h=0.36 = 0.545(f_m¢)_e/h=0 and (f_m¢)_e/h=0.45 = 0.319(f_m¢)_e/h=0. In addition, the behavior of the interlocking block masonry under eccentric loading is also elucidated including the stress-strain relationship, the modulus of elasticity, the failure characteristic and the movement characteristic in the central part.
