| چکیده | ||
| یکی از موضوعات با اهمیت در حوزه مهندسی ایجاد یک فضای آرام و حس امنیت برای ساکنین ساختمان‌ها به ویژه سازه‌های بلندمرتبه در برابر نیروی زلزله و باد می‌باشد، به‌همین منظور استفاده از سیستم‌های کنترلی جهت کاهش ارتعاش سازه در برابر بارهای دینامیکی مورد توجه قرار گرفته است. میراگر مایع تنظیم‌شده یک ابزار پرکاربرد و مقرون به‌صرفه برای کنترل ارتعاشات سازه تحت بارهای جانبی دینامیکی می‌باشد. در این پژوهش سازه بلندمرتبه استاندارد تحت تحریک‌های زلزله حوزه دور و نزدیک و باد در نرم‌افزار انسیس شبیه‌سازی شده است و اندرکنش باد و سازه مورد بررسی قرار گرفته است. به منظور کاهش پاسخ‌های سازه بلندمرتبه تحت رکوردهای زلزله حوزه دور (السنترو 1940 و هاچینو 1968)، رکوردهای زلزله حوزه نزدیک (نورثریج 1994 و کوبه 1995) و نیروی باد از یک میراگر مایع تنظیم‌شده استفاده شد. پاسخ‌های سازه از قبیل جابجایی، سرعت، شتاب، فشار وارده و خطوط جریان باد بر روی دیواره‌های سازه مورد آنالیز قرار گرفته است و همچنین، رفتار آئرودینامیک سازه در برابر نیروی باد بررسی شده است. نتایج بدست آمده نشان می‌دهد که میراگر مایع تنظیم‌شده می‌تواند جابجایی سازه را به‌طور میانگین تحت رکوردهای حوزه دور تا 16 درصد، رکوردهای حوزه نزدیک 0/5 درصد و تحت باد تا 13 درصد کاهش دهد. | ||

| چکیده [English] | ||
| One of the essential issues in structural engineering is preparing resident comfort and a sense of security for the residents of high-rise structures against earthquakes and strong winds. Therefore, the use of control systems has been considered under dynamic loads. Tuned liquid damper is an affordable and helpful device for controlling the vibrations of the structure under dynamic lateral loads. In this study, a standard high-rise structure has been modeled in ANSYS software under earthquakes (far and near-field) and wind and the interaction between wind and structure has been investigated. Tuned Liquid Damper was used to reduce the responses of the structure under far-field records (El-Centro 1940 and Hachinohe 1968), near-field records (Northridge 1994 and Kobe 1995), and wind. The responses of the structure such as displacement, velocity, acceleration, pressure, and streamline around the structure have been analyzed and also, the aerodynamic behavior of the high-rise structure against the wind has been investigated. Averagely, the results show that the Tuned Liquid Damper could reduce the maximum displacement of the structure to 16% under far-field records, 0.5% under near-field records, and 13% under the wind. | ||
