Steel Plate Shear Wall (SPSW) is considered as one of the efficient lateral loading resisting systems used in areas with high seismicity. The present study investigates the behavior of plates with circular cut-outs under different infill plate boundary conditions. The effect of opening dimensions on the behavior of steel plate shear walls, boundary element stiffness and steel infill plate interconnection are studied computationally. The prediction equations for steel plate shear wall systems with circular openings are proposed based on the regression analysis. For this purpose, experimental laboratory tests were initially verified under cyclic loading condition, and the corresponding modes of behavior are captured and validated. Subsequently, more than 30 numerical models with different boundary elements and openings’ conditions are constructed and compared under cyclic loading to obtain the backbone curves. The results indicate that any increase in the opening dimensions leads to the reduction of the ultimate strength, stiffness, ductility, and energy absorption in proportion to the effective wall height. Furthermore, any increase in the stiffness of the SPSW’s beams and columns improves the overall hysteric performance of the steel plate shear wall. It is shown that the infill plate interconnection conditions, specifically with the beam member, has a significant effect on the tension field action development inside of the infill plate leading to proper post-buckling resistance of the steel plate shear walls.

钢板剪力墙（SPSW）被认为是在地震烈度较高的地区使用的有效的横向抗荷载系统之一。本研究调查了在不同填充板边界条件下具有圆形切口的板的行为。通过计算研究了开口尺寸对钢板剪力墙性能，边界元刚度和钢板填充板互连的影响。在回归分析的基础上，提出了圆形开口钢板剪力墙系统的预测方程。为此，最初在循环负载条件下验证了实验室实验测试，并捕获并验证了相应的行为方式。后来，构造了30多个具有不同边界元素和开口条件的数值模型，并在循环载荷下进行了比较，以获得主干曲线。结果表明，开口尺寸的任何增加都会导致极限强度，刚度，延展性和能量吸收的降低与有效壁高成比例。此外，SPSW梁和柱的刚度的任何增加都会改善钢板剪力墙的整体滞后性能。结果表明，填充板的互连条件，特别是与梁构件的互连条件，对填充板内部的拉力场作用的发展有重大影响，从而导致钢板剪力墙具有适当的抗屈曲性。结果表明，开口尺寸的任何增加都会导致极限强度，刚度，延展性和能量吸收的降低与有效壁高成比例。此外，SPSW梁和柱的刚度的任何增加都会改善钢板剪力墙的整体滞后性能。结果表明，填充板的互连条件，特别是与梁构件的互连条件，对填充板内部的拉力场作用的发展有重大影响，从而导致钢板剪力墙具有适当的抗屈曲性。结果表明，开口尺寸的任何增加都会导致极限强度，刚度，延展性和能量吸收的降低与有效壁高成比例。此外，SPSW梁和柱的刚度的任何增加都会改善钢板剪力墙的整体滞后性能。结果表明，填充板的互连条件，特别是与梁构件的互连条件，对填充板内部的拉力场作用的发展有重大影响，从而导致钢板剪力墙具有适当的抗屈曲性。SPSW的梁和柱的刚度的任何增加都会改善钢板剪力墙的整体滞后性能。结果表明，填充板的互连条件，特别是与梁构件的互连条件，对填充板内部的拉力场作用的发展有重大影响，从而导致钢板剪力墙具有适当的抗屈曲性。SPSW的梁和柱的刚度的任何增加都会改善钢板剪力墙的整体滞后性能。结果表明，填充板的互连条件，特别是与梁构件的互连条件，对填充板内部的拉力场作用的发展有重大影响，从而导致钢板剪力墙具有适当的抗屈曲性。
