چکیده

در این مقاله از کنترل هماهنگ‌ساز جهت سازه پنج طبقه Kajima Shizuoka تحت رکورد زلزله السنترو استفاده نموده و موفقیت آن در حفاظت لرزه‌ای ساختمان مورد ارزیابی قرار گرفته است. با توجه به جفت هماهنگ‌ساز، مقادیر اندازه تغییرمکان ، تغییرمکان نسبی بین طبقات(ε )  و خطای موقعیت توأم EC را موردبررسی قرار داده‌ایم. با استفاده از معادله دیفرانسیل مربوط به معادله حرکت و معادله حالت، ضرایب را مشخص و سپس با توجه به استفاده از نرم تابع و حل معادله ریکاتی کنترلر  را طوری طراحی نمودیم تا کنترلر نسبت به عدم قطعیت و دینامیک مدل نشده، مقاوم و از عملکرد خوبی برخوردار باشد. نتایج را به‌صورت شکل‌های مقایسه‌ای به دست آورده و ارائه گردید.

چکیده [English]

In this paper, synchronized control is used for five story structure of Kajima Shizuoka under the EL - Centro earthquake load  ( 1940) seismic record. According to coupled values of displacement, drift and position error the related partial differential equation for motion and state is solved successfully. The Riccati equation is solved based on the close loop transfer function with respect to uncertainty parameters and random dynamic processes. Numerical simulations along with comparisons are made to evaluate the efficiency of this hybrid technique.
