Assessment and Non-Liner Analysis (Finite Element) of Non-Buried Steel Tank under the Interaction between Structure and Liquid

چکیده مقاله

The study of seismic behavior of ground flexible steel tank, the specification of input earthquake and other effective parameters in response to these structures in regard to interaction of structure and liquid are among the purposes of this paper. So all structure and liquid contexts are assessed by elements with freedom degree of model displacement, the interaction between structure and liquid using the constrained equations. To modeling and analyses, the three-dimension model is used. Analyses results indicated maximum FOUN MISES stress of tank in same conditions in regard to the geometric characteristics is increased by increased height to diameter ratio and also the increased H/D ratio, will increase the susceptibility. Also the increased wall thickness caused to increase the hardness of tank which decreasing the tank thickness lead to increasing FOUN MISES stress and also increased susceptibility. Decreasing max acceleration of input record lead to lower FOUN MISES stress and lower susceptibility.
