چکیده

در آنالیزهای حجیم دینامیکی هزینه محاسباتی و زمان تحلیل بالا است، لذا نیاز به مدل‌های ساده شده ای می باشد که در مقایسه با مدل دارای جزئیات با دقت مناسب و قابل قبول، زمان فرآیند تحلیل را به میزان قابل توجهی کاهش دهد. در این تحقیق مدل ساده شده چند درجه آزادی برای سیستم دوگانه قاب خمشی-دیوار برشی با پلان منظم پیشنهاد شده است. برای دیوار برشی از مدل MVLEM و برای قاب خمشی از مدل قاب جایگزین بهره گرفته شده است. مدل MVLEM از المان های محوری تشکیل شده که رفتار خمشی دیوار برشی را به خوبی مدلسازی می کنند و مدل قاب جایگزین نیز مدل قاب یک دهانه‌ای است که جایگزین قاب های خمشی بتنی چند دهانه مدل می شود. در انتها دقت و سرعت مدل ساده شده نسبت به مدل اصلی دارای جزییات بررسی گردید. نتایج آنالیزها نشان می‌دهد که مدل ساده شده پاسخ‌های لرزه ای را با خطای کمتر از 20 درصد و با زمان آنالیز کمتر از 30 برابر نسبت به مدل دارای جزییات ارائه می‌دهند.

چکیده [English]

Mass dynamic analysis of structures requires high computational cost which leads to time consuming process. Therefore, it is necessary to use simplified models that significantly reduce the time of the analysis with appro-priate and acceptable accuracy compared to the detailed model. In this research, a simplified model of multi degrees of freedom for the dual system of moment resisting frame and shear wall with regular plan is proposed. MVLEM model is used for shear wall and Substitute Frame is used for RC moment resisting frame. The MVLEM model consists of axial elements that simulate the flexural behavior of the shear wall and the substi-tute frame uses one bay frame instead of multi-bay moment resisting frames. In the end, the accuracy and speed of modeling and analysis of the simplified model compared to the original model as a detailed frame. The results show that the simplified model provides seismic responses with less than 10% error and analysis time less than 30 times compared to the detailed model.
