| اخیراً به کارگیری راهکارهای افزایش مقاومت و میراییِ سازه ها در برابر بارهای لرزه ای، با هدف افزایش ایمنی در برابر کاهش هزینه اجرا و نگهداری، مورد توجه محققین قرار گرفته است. از جمله مهمترینِ این راهکارها می توان به ترکیب قاب های فولادی به همراه میراگرهای ویسکوز اشاره نمود. همچنین در زمینه کنترل غیرفعال سازه‌ها، یکی از توانمندترین ابزارها، میراگرهای ویسکوز می‌باشند که در جهت جذب انرژی زلزله و اتلاف آن جهت کاهش پاسخ سازه مورد استفاده قرار می‌گیرند. لذا هدفِ این پژوهش تحلیل اثر این سیستم سازهای بر پاسخ قاب های معیار SAC که در 3، 9 و 20 طبقه احداث شدهاند، در مقابله با بارهای لرزه ای می باشد. برای بررسی این موضوع در این مطالعه ابتدا مدل عددی میراگر ویسکوز با استفاده از نرمافزار آباکوس ایجاد شده است. در ادامه، اثر اعمال شتاب گسل دور و نزدیک زلزله های امپریالولی، لوماپریتا و نورثریج بر رفتار این سیستم سازهای به طور جداگانه ارزیابی شده و نتایج شامل دریفت طبقات، ظرفیت باربری (به صورت برش پایه بیشینه) و جذب انرژی سازه (در دو حالت کار خارجی و انرژی کرنشی) مورد بحث و بررسی قرار گرفته است. نتایج به طور میانگین برای سه سازه مورد بحث، بیانگر کاهش 200 درصدیِ دریفت، افزایش 30 درصدی ظرفیت باربری و افزایش 35 درصدی جذب انرژی سازه های فولادی معیار SAC پس از اعمال میراگر ویسکوز بوده است. | ||

| چکیده [English] | ||
| Researchers have recently considered ways to increase the strength of and damping of the structures against earthquake loads so as to reduce maintenance and maintenance costs while enhancing safety. These solutions include the combination of steel frames with viscous dampers as the most vital part. Additionally, one of the most powerful tools in passive control is viscous dampers, which absorb earthquake energy and reduce the structure's response to earthquakes. Therefore, we have undertaken this study to investigate the response of standard SAC frames, built-in three, nine, and twenty floors, by applying this structural system to seismic loadings. The issue was first investigated using the Abaqus software package's numerical model of the viscous damper. Then, the effect of applying acceleration of faults of far and near-field Imperial Vali, Lomaprita, and Northridge earthquakes on the behavior of this structural system is evaluated separately. The results include floor drift, load-carrying capacity (as maximum base shear), and energy absorption of the structure (in two External working modes and strain energy) are discussed. Applied viscous dampers resulted in an average 200% decrease in drift, a 30% increase in load-carrying capacity, and a 35% increase in energy absorption in SAC standard steel structures after the application of these dampers. | ||
