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.

چکیده [English]

The seismic behavior of the on ground bipartite elliptical tanks has been investigated in the current study. Basically, the tank is a structure used to store different types of fluid, and it is also widely used in refineries, sewage treatment plants and factories in the form of on ground and elevated tanks made from concrete and steel. The monoplete and double on ground elliptical tanks have been dinamically analyzed under Cape and Tabas earthquakes simoultaneously in the longitudinal and transverse directions in various conditions of prolateness and slenderness of the tank and the maximum impulsive pressure and the maximum wave height parameters of corresponding cases have been compared with eachother in the current research. By study of the concluded diagrams, it was revealed that the reduction percent of the maximum impulsive pressure and the maximum wave height parameters due to partitioning of the tank is higher in more slender tanks. It also was revealed that the reduction percent of the maximum impulsive pressure and the maximum wave height parameters due to partitioning of the tank is higher in more prolate tanks.
