<p>‌The behavior of double diagonal corrugated plate-reinforced flat steel shear walls (SSWs) has been studied in this study. Corrugated double plates were used in this research with 5 angles of 90°, 60°, 45°, 30°, and 0° to the vertical axis. Also, three corrugation angles were used for the trapezoidal corrugated plate, including 30°, 45°, and 60°. The reinforcement corrugated plate was used in three thicknesses of 2, 4, and 6&#xa0;mm. According to the study’s findings, reinforcing a flat wall using corrugated plates of varying thicknesses and angles improved the wall’s maximum strength by 6.1–40.5%. Also, the initial stiffness of hardened SSWs has increased by a minimum of 1% and a maximum of 47.7% compared to the control sample. The results also showed that the increase in the thickness of the reinforced corrugated plate directly led to an increase in the lateral bearing capacity and initial stiffness. Furthermore, due to the reinforcement of the flat plate, energy absorption has increased between 4.9 and 40%. Also, findings indicate that stiffened materials have a higher equivalent viscous damping than unstiffened samples.</p>

摘要

‌The behavior of double diagonal corrugated plate-reinforced flat steel shear walls (SSWs) has been studied in this study. Corrugated double plates were used in this research with 5 angles of 90°, 60°, 45°, 30°, and 0° to the vertical axis. Also, three corrugation angles were used for the trapezoidal corrugated plate, including 30°, 45°, and 60°. The reinforcement corrugated plate was used in three thicknesses of 2, 4, and 6 mm. According to the study’s findings, reinforcing a flat wall using corrugated plates of varying thicknesses and angles improved the wall’s maximum strength by 6.1–40.5%. Also, the initial stiffness of hardened SSWs has increased by a minimum of 1% and a maximum of 47.7% compared to the control sample. The results also showed that the increase in the thickness of the reinforced corrugated plate directly led to an increase in the lateral bearing capacity and initial stiffness. Furthermore, due to the reinforcement of the flat plate, energy absorption has increased between 4.9 and 40%. Also, findings indicate that stiffened materials have a higher equivalent viscous damping than unstiffened samples.
