Analysis proposes effective buckling-restraint designs for steel plate shear walls, enhancing stability.
Steel plate shear walls are structural units widely used to improve the overall lateral stiffness of steel frame structures. It is essential to prevent out-of-plane instability during normal service to ensure the unit fulfills its shear resistance. This paper analyzes the stability of a novel portal steel plate shear wall under various stress conditions. Based on its structural characteristics and practical design needs， a simple and practical buckling-restraint design method is proposed. The main innovations of this method are： 1） Designers can determine the required parameters through simple calculations or graphical methods without performing secondary analysis for the buckling-restraint design. 2） It provides multiple effective buckling-restraint stiffening schemes for portal steel plate shear wall elements， which can be directly selected based on relevant conditions and requirements.
