This paper systemly studies the deformation behavior of the grouted concrete block masonry. Based on the experimental research, the constitutive relationship of compression and shear is put forward, and the calculating formula of elastic module and Poisson ratio of the grouted concrete block masonry are obtained, which can be used for reference ln researching the grouted concrete block masonry.
Keywords: grouted concrete block masonry; constitutive relation; elastic module; Poisson ratio
