An eccentric low cyclic horizontal loading has been applied to the spatial structure of a three-storied short-per shear wall, which has been designed according to the current national Design Specification for Special-Shaped Column Structures. A research has been made of the crack development and structural stress of the structures under the torsional loading. Experimental results show that the short-pier shear wall structure is a typical structure with strong limbs and weak beams, its tie-beam end being the weak region of the structure. The plastic hinges at the end of the tie-beam effectively consume the seismic energy, and the part near the outer edge of the wall limbs, also a weak component of short-limb shear wall structure, whose tension has been strengthened under the double effects of the torque and the relatively large bending moment of the storey. The shear force is transferred through the baroclinic rod mechanism inside the joint of beams, which has been under the multiple effects of bending, shear and torsion.
