| سیستم دیوار برشی فولادی به عنوان سیستم مقاوم در برابر نیروهای جانبی به دلیل دارا بودن سختی، ظرفیت بالا، شکل‌پذیری زیاد و جذب و استهلاک انرژی قابل‌توجه نظر محققان را به خود جذب کرده است. از طرفی، بهسازی و تعمیر این سیستم در سطوح لرزه‌ای پایین و متوسط از لحاظ اقتصادی به‌صرفه نمی‌باشد؛ بنابراین برای محدود نمودن آسیب‌ها سیستم نوین دیوار برشی فولادی با میراگر ویسکوز به عنوان سیستم مقاوم در برابر بارهای جانبی ارائه گردیده است. در این مقاله رفتار و عملکرد سیستم ترکیبی دیوار برشی فولادی با ورق نازک دارای میراگر ویسکوز به روش عددی با استفاده از نرم‌افزار OpenSees مورد مطالعه قرار گرفته است. سازه‌هایی در دو حالت دارای دیوار برشی فولادی تنها و دیوار برشی فولادی با میراگر ویسکوز، تحلیل و طراحی شده و عملکرد لرزه‌ای و ارزیابی فروریزش آنها مورد مطالعه قرار گرفته است. در ادامه به بررسی اندرکنش میان دیوار برشی فولادی و میراگر ویسکوز پرداخته شده است. نتایج نشان می‌دهد با افزایش طبقات و غالب شدن مود خمشی بر سازه، اثر تداخلی تغییر شکل‌های دیوار و میراگر، اندرکنش بین دیوار برشی فولادی و قاب مهاربندی میراگر ویسکوز را نتیجه می‌دهد. نتایج ارزیابی فروریزش نشان می‌دهد استفاده از میراگرهای ویسکوز در کنار سیستم دیوار برشی فولادی در سازه‌های 8، 16 و 24 طبقه موجب افزایش چشمگیر نسبت حاشیه‌ای فروریزش به ترتیب 100%، 92% و 66% و همچنین کاهش احتمال سالیانه فروریزش به ترتیب 75%، 79% و 58% گردیده که نشان از تأثیرگذاری میراگر ویسکوز داشته و اهمیت استفاده از این جزء را روشن می‌نماید. | ||

| Steel plate shear wall systems have attracted researchers' attention as lateral force-resisting systems, owing to their high stiffness, capacity, considerable ductility, and energy dissipation. On the other hand, retrofitting and repairing these systems is uneconomical for low and medium seismic levels. Therefore, to limit damage, a new steel plate shear wall system equipped with viscous dampers has been proposed as a system capable of resisting lateral loads. In this paper, the behavior and performance of a composite thin steel plate shear wall system with viscous dampers is investigated numerically using OpenSees software. Structures are analyzed and designed in two cases: one with steel plate shear walls alone and one with steel plate shear walls coupled with viscous dampers. Their seismic performance and collapse assessment are studied. Furthermore, the interaction between the steel shear wall and the viscous damper is examined. Results show that with the increasing number of stories and the dominance of flexural mode over the structure, the interfering deformations of the wall and damper produce interaction between the steel plate shear wall and the viscous damper bracing frame. Collapse assessment results demonstrate that utilizing viscous dampers along with the steel plate shear wall system in 8, 16, and 24-story structures leads to the significant increase in collapse margin ratio by 100%, 92%, and 66% respectively. It also reduces annual collapse probability by 75%, 79% and 58% respectively, which indicates the influence of the viscous damper and underscores the importance of using this component. | ||
