In this paper, the author by 12 slices fly ash brick masonry wall (solid brick and cork brick) slice, 2 slices of sintering ordinary brick masonry wall under cyclic horizontal and vertical loading experiment (including different normal stress, different mortar strength, and presence of post) is given, according to three of the most popular theory. The author suggest the autoclaved fly ash brick masonry proposed formula with Changsha university of science and technology, and Chongqing university the relative test data after that compared, autoclaved fly ash brick wall shear strength calculation formula is recommended. The method of the present paper may provide an important reference to engineering design as well as code revision.
