The seismic resistance properties of the structures of short-limbed walls (SLW) were explored by horizontal cyclic loading experiments on 6 SLW specimens including 3 flanged and 3 non-flanged. The ratios of the depth to the width of the 3 specimens in each group were 5, 6.5 and 8, respectively. For non-flanged SLW structures with a small depth-to-width ratio, longitudinal bars in the limb yield first;and for those with a large depth-to-width ratio, stirrups in a linking beam yield first. For a structure with different depth-to-width ratio varying from 5 to 8, the failure mode is different. Correspondingly, different calculation model should be used in the design and engineering of the structure. For flanged SLW structures with whatever depth-to-width ratio, longitudinal bars in a flange or limb yield first. The SLW structures with a depth-to-width ratio of 6.5 exhibit the best comprehensive seismic resistant property and flanged walls have a better ductility than non-flanged ones.
