In dual-opening steel shear walls, the performance of the panel located in between of the openings has been studied using a beam; which would show flexural, shear or combined behavior, depending on its “height to width” ratio. By applying bilateral stiffeners on both sides of the central panel, the extreme ones will act as boundary members of the central panel which may now be compared to SPSW .It is necessary for the cross-sectional area of stiffeners to meet minimum requirements, so that the shear yielding of the central panel to occur prior to flexural yielding of its side stiffeners. In addition, the “height to width” ratio of the central panel has a dominant role in predicting its behavior. In the present paper, the stiffened central panel has been analytically studied using ABAQUS package.It has been concluded that for stiffened dual-opening steel shear walls, properly selected “height to width” ratio would result in a dominant shear behavior for the central panel.
