Seismic Effect of Height Fluid Filling on Storage Cylindrical Container

چکیده
Liquid storage cylindrical containers are built for storing a variety of liquids. The seismic behavior of tanks is, however, quite complex problem. The interaction of tank and liquid can be simplified with the concept of generalized single-degree-of-freedom systems representing the convective, rigid impulsive and flexible impulsive vibration modes. This paper presents the theoretical background for cylindrical tanks fixed to rigid foundation under earthquake loading, describing the fluid hydrodynamic pressure and the seismic response of liquid storage tank. The base shears, the bending moment and overturning moment are calculated by using the response spectra for risk region of Slovakia, B category of subsoil. The seismic analysis was made on the ground supported cylindrical concrete tanks with considering of partial fulfillments. Key-Words: Container, fluid, earthquake, pressure, shear, moment.

Study on the dynamic behavior of cylindrical steel liquid storage tanks using finite element method
Dynamic behavior of ground supported cylindrical storage tanks (CST) is of crucial importance because of its applications in industrial complexes. Seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. Five CSTs with different height to diameter ratios, three CSTs with the same height and diameters but various fluid heights and one CST with t...
متن کاملEstimation of Sloshing Wave Height in Broad Cylindrical Oil Storage Tanks Using Numerical Methods
Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of cylindrical tanks leads to serious consequences.

Therefore, evaluation of seismic performance of these str...
متن کاملIntroduction of Air Cushion to Reduce Seismic Demand in Cylindrical Water Storage Tanks
Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...
