TY - JOUR ID - TI - STRUCTURAL ANALYSIS OF THE SINGLE AND GROUP FUEL TANKS UNDER THE INFLUENCE OF SEISMIC LOADS IN BASRA GOVERNORATE AU - Abdulameer Q. Hasan PY - 2019 VL - 10 IS - 4 SP - 42 EP - 52 JO - KUFA JOURNAL OF ENGINEERING مجلة الكوفة الهندسية SN - 20715528 25230018 AB - In this paper, the finite element ANSYS software was used to study the seismic behavior ofcylindrical fuel storage tanks in west of Basra governorate. Single and group tanks areanalyzed under free vibration (empty and full tanks) and under the El-Centro earthquakecomponent for an impulsive case and full tank with fuel. The interaction between tanks walland internal fuel was considered. The study includes Hoop forces, bending moment, shearforce, horizontal displacement and hydrodynamic pressure. Also, the reflection point forbending moment and shear force for tank wall is estimated.This study shows that the response of a single tank is larger than group tanks, and the hoopforce decreases about (10-17) %, while the pressure and displacement decrease about (5-10)%, and the shear force and bending moment are decreased about (37-42) %. The increase intank diameter leads to increase the response of tank. The Time has come to the understandingthat the fixed support of tank is more stable than hinge support.
