چکیده

در این مقاله رفتار و عملکرد لرزه‌ای سازه‌های بلند با سیستم سازه‌ای لوله در لوله به‌عنوان یکی از سیستم‌های باربر جانبی با هسته بتنی دارای بازشو در دیافراگم مورد مطالعه قرار می‌گیرد. به منظور بررسی تأثیر سیستم لوله در لوله با هسته مرکزی بر رفتار لرزه‌ای سازه بلند، مدل سازه‌ای در دو حالت با لوله داخلی و بدون در نظر گرفتن لوله داخلی مورد ارزیابی قرار می‌گیرد. جهت بررسی رفتار لرزه‌ای مدل سازه‌ای از سه روش تحلیل استاتیکی معادل، تحلیل دینامیکی تاریخچه زمانی غیرخطی و تحلیل استاتیکی غیرخطی (پوش‌اور) استفاده می‌شود. همچنین از یک مدل سازه‌ای 25 طبقه با سیستم لوله در لوله با هسته بتنی استفاده می‌شود به طوری‌که این مدل سازه‌ای در طبقات آخر دارای بازشو در دیافراگم می‌باشد. نتایج بدست آمده از مطالعات صورت گرفته نشان می‌دهد که استفاده از هسته بتنی به عنوان لوله مرکزی موجب کاهش محسوسی در جابجایی جانبی و دریفت طبقات می‌شود. همچنین نتایج بدست آمده از تحلیل استاتیکی غیرخطی (پوش‌اور) نشان می‌دهد که با استفاده از هسته بتنی مرکزی، ظرفیت نهایی سازه و شکل‌پذیری سازه افزایش چشم‌گیری پیدا می‌کند. نتایج بدست آمده از تحلیل دینامیکی تاریخچه زمانی غیرخطی نشان می‌دهند که برای این سیستم سازه‌ای روش استاتیکی غیرخطی از دقت خوبی در محاسبه حداکثر تغییرمکان سازه برخوردار می‌باشد.

چکیده [English]

In this paper, the seismic behavior of reinforced concrete (RC) high-rise buildings with frame-core tube systems as one of the lateral bearing systems are studied. In order to investigate the effect of the core tube system on the seismic behavior of the high-rise building, the structural model is evaluated in two cases with the inner core tube and without the inner core tube. Three methods of equivalent static analysis, dynamic nonlinear time history analysis and nonlinear static analysis (push-over analysis) are used. Also, a 25-story high-rise building with a frame-core tube system having voids in the last floors is implemented. The results showed that the use of RC core as a central tube significantly reduces the lateral displacement and drift of floors. Also, the results obtained from the nonlinear static analysis indicated that using the central RC core, the ultimate capacity of the building as well as the ductility of the building increase significantly. Finally, the results obtained from the nonlinear time history showed that the nonlinear static analysis have good accuracy in calculating the maximum displacement of the structure.
