| در این مقاله به طراحی مکانیزم میراگر جرمی هماهنگ شده ی نیمه فعال (SATMD) با میرایی متغیر برای کاهش پاسخ سازه های غیرخطی تحت اثر زلزله پرداخته شده است. جهت تعیین دستورهای مناسب برای انتخاب میرایی در هر لحظه، الگوریتم کنترل نیمه فعالی برای سازه‌های غیرخطی بر مبنای الگوریتم بهینه ی آنی غیرخطی و قانون کنترل برشی تهیه شده است که برای طراحی بهینه ی سیستم کنترل، پارامترهای طراحی از حل یک مسأله ی بهینه‌سازی با تابع هدف کمینه کردن ماکزیمم پاسخ سازه با استفاده از الگوریتم ژنتیک (GA) تعیین شده است. به منظور آنالیز عددی و ارزیابی روش پیشنهادی، قاب 8 طبقه برشی دو بعدی، با رفتار غیرخطی هیسترسیس تحت اثر اغتشاش سفید در نظر گرفته شده و به طراحی مکانیزم SATMD پرداخته شده است. نتایج بررسی‌ها نشان می‌دهد که الگوریتم پیشنهاد شده دارای کارایی مناسب برای طراحی سیستم SATMD با میرایی متغیر برای سازه های غیرخطی می باشد. همچنین مقایسه ی عملکرد مکانیزم SATMD با میراگر جرمی هماهنگ شده غیر فعال و فعال نشان می دهد که عملکرد سیستم SATMD در کاهش پاسخ‌های سازه‌های غیرخطی بهتر از عملکرد سیستم میراگر جرمی هماهنگ شده غیرفعال بوده اما در مقایسه با مکانیزم میراگر جرمی فعال عملکرد ضعیف تری داشته است. | ||

| چکیده [English] | ||
| In this paper, designing semi-active tuned mass damper (SATMD) for reducing the response of nonlinear frame structures under earthquake excitations has been studied. The semi- active characteristic of the control system has been achieved by modifying the damping in each time step. To determine the appropriate command signals for selecting the damping coefficient of SATMD, a semi-active control algorithm based on nonlinear instantaneous optimal control and Clipped Optimal Control concept has been developed. Also for optimal design of the control system, the design parameters have been determined by solving an optimization problem that minimizes the maximum response of the structure using genetic algorithm (GA). As numerical example, for an eight-storey nonlinear shear frame with bilinear hysteresis behavior under white noise excitation, SATMD has been designed. The results of numerical simulations show the capability of the proposed method for determination of control signal as well as the effectiveness of the SATMD mechanism in reducing the response of the nonlinear structures under earthquake excitation. In addition, comparing the performance of SATMD with those of passive and active tuned mass dampers shows that SATMD has worked better than passive tuned mass damper while active mass damper shows better performance than SATMD | ||
