There is a super high?rise shear wall structure in Chongqing, of which a large range of the bottom is through two floors, and the shear wall of the two sides are in tension. I?shaped steel was added to the tension wall and the wall through two floors in the design phase. In this paper, improving of the elastic?plastic properties of shear wall by I?shaped steel was analyzed, the selection and layout of the I?shaped steel were described,the construction of the stirrups outside of the I?shaped steel and lengthening of the I?shaped steel and the foundation designing of the shear wall with I?shaped steel were elaborated, the anchorage and connection of the longitudinal reinforcement of the beam in the shear wall were designed to deepen. The effectiveness and feasibility of I?shaped steel settings was demonstrated.
