چکیده

در این تحقیق، رفتار لرزه­ای مخازن روزمینی بیضوی دوقلو مورد مطالعه قرار گرفته‌است. اساساً مخزن سازه­ای است که برای ذخیره‌ی انواع مایع به‌کار می­رود و در انواع زمینی و هوایی و نیز بتنی و فولادی کاربرد گسترده­ای در تصفیه­خانه­ها و پالایشگاه­ها و کارخانه­ها دارد. در این تحقیق مخازن بیضوی روزمینی یک­قلو و دوقلو در حالت­های مختلف کشیدگی و لاغری مخزن، تحت زلزله­های کیپ و طبس به‌طور هم‌زمان در جهات طولی و عرضی بااستفاده از نرم‌افزار فلوئنت به‌روش حجم محدود، تحت تحلیل دینامیکی قرار گرفته­اند و پارامترهای فشار ماکزیمم ضربه­ای و ارتفاع ماکزیمم موج حالت­های متناظر با هم مقایسه شده­اند. با بررسی نمودارهای به‌دست‌آمده مشخص شد که درصد کاهش پارامترهای فشار ماکزیمم ضربه­ای و ارتفاع ماکزیمم موج به‌واسطه‌ی تقسیم مخزن، در مخازن لاغرتر بیشتر است. هم‌چنین مشخص گردید که درصد کاهش پارامترهای فشار ماکزیمم ضربه­ای و ارتفاع ماکزیمم موج به‌واسطه‌ی تقسیم مخزن، در مخازن کشیده­تر بیشتر می­باشد.
