研究填充板中心有圆形穿孔的未加劲薄钢板剪力墙的性能。给出了中心穿孔钢板剪力墙的剪切强度公式。对具有不同高宽比和不同穿孔直径的一系列单层穿孔钢板剪力墙进行分析,以此评估提出的抗剪强度公式。建议公式的计算结果与非线性弹塑性分析结果吻合较好。提出的抗剪强度公式适用于4肢和6肢穿孔钢板剪力墙边界柱的设计。建议公式计算的指定穿孔剪力墙边界柱的承载力,与非线性地震反应分析结果进行了对比,建议公式能够很好地预测边界柱的承载力。
The performance of circular stiffened sheet steel shear walls with a round perforation in the center of the filling plate was studied. The shear strength formula of the center pierced steel shear wall is given. A series of single-layer perforated steel plate shear walls with different aspect ratios and different perforation diameters were analyzed to evaluate the proposed shear strength formula. The calculated result of the proposed formula is in good agreement with the nonlinear elasto-plastic analysis. The proposed shear strength formula is suitable for the design of boundary columns of 4-limbs and 6-limb perforated steel plate shear walls. The proposed formula for calculating the bearing capacity of the boundary columns with designated perforated shear walls is compared with the results of nonlinear seismic response analysis. It is suggested that the formula can well predict the bearing capacity of the boundary columns.
