| description | Abstract This paper proposes a novel multi-grids steel plate shear wall with inclined slots (called MSPSW). This MSPSW composed of the steel plates with inclined slots, precast concrete panels, the transverse and longitudinal (T&L) connecting stiffeners, and external frame components. Smaller single plates can be used in the design and installation process since the space size of individual frames inside the frame is reduced as a result of the T&L connecting stiffeners. The direction of inclined slots in the adjacent grids is opposite, which makes the lateral resistance and stiffness close to symmetry. Numerical analysis is conducted to evaluate the seismic behavior. With the correct finite element model, finite element analysis is performed on the key parameters of MSPSW, such as the cross-sectional dimension of T&L connecting stiffeners, the thickness of steel plate, the width of inclined slots and the width of plate slot strips. The Mises distribution and development regular pattern of MSPSW are also explored. The FE numerical analysis discovered that the MSPSW increased the bearing capacity and energy consumption capacity of the members due to the installation of T&L connecting stiffeners. Additionally, the thickness required for concrete panels is lowered when the components are subjected to cyclical loads. Finally, the internal force development curves in frame beams and columns are extracted, it can be found that the internal forces become smaller, which weakens the demand of frame members. The theoretical calculation formulas of the maximum internal forces of frame beams and columns are provided. |
