［摘要］提出一種由兩片內填薄鋼板組成的新型雙向斜開槽鋼板剪力墻。每片鋼板開設與柱中心線呈45°角的系列斜槽并反向布置，兩片鋼板通過橡膠層粘接。在往復水平荷載作用下，雙層斜開槽鋼板中總有一層鋼板其斜向板帶處于受拉狀態(tài)，因此，剪力墻系統(tǒng)表現(xiàn)出穩(wěn)定的滯回性能，同時受拉板帶為另一層鋼板中受壓板帶提供面外支撐，顯著提高了受壓鋼板的屈曲承載力，形成自防屈曲機制。通過有限元方法研究了高厚比、斜槽寬度及板帶寬度對雙向斜開槽鋼板剪力墻抗剪承載力的影響。根據開斜槽鋼板剪力墻的承載機制，理論推導了雙層斜開槽鋼板剪力墻承載力的計算公式，并以2 000mm×2 000mm鋼板剪力墻為例，對其有限元模擬方法進行了驗證。最后給出了雙層斜開槽鋼板剪力墻的設計建議：斜槽寬度40mm、板帶寬度200mm的雙層斜開槽鋼板剪力墻的抗剪承載力可采用簡化計算公式乘以放大系數1-24來計算。

Abstract:A new double-layer inclined slotted steel plate shear wall composed of two sheets of filled steel sheets was proposed. Each steel plate was provided with a series of inclined slots at an angle of 45° to the center line of the column and arranged in reverse, and the two steel plates were bonded by a rubber layer. Under the action of reciprocating horizontal load, there was always a layer of steel plate in the double-layer inclined slotted steel plate, and the inclined plate strip was in the tension state. Therefore, the shear wall system exhibited stable hysteresis performance, and at the same time, the tension plate strip provided the out-of-plane support for the pressure-bearing plate strip of another steel plate, which significantly improved the buckling bearing capacity of the pressed steel plate and formed a self-defense buckling mechanism. The effects of high-thickness ratio, inclined slot width and strip width on the shear capacity of double-layer inclined slotted steel shear wall were studied by finite element method. According to the bearing mechanism of the inclined slotted steel plate shear wall, the calculation formula of the bearing capacity of the double-layer inclined slotted steel plate shear wall was derived theoretically. Taking the 2 000mm×2 000mm steel plate shear wall as an example, the finite element simulation method was carried out for verification. Finally, the design proposal of the double-layer inclined slotted steel plate shear wall was given. The shear capacity of the double-layer inclined slotted steel plate shear wall with the inclined slot width of 40mm and a strip width of 200mm can be calculated by the simplified calculation formula multiplied by a factor of 1-24.
