Finite element analysis of a seismically excited cylindrical storage tank, ground supported, and partially filled with liquid

Book ·
OSTI ID:7035774
The structure under consideration is an elastic cylindrical liquid storage tank attached to a rigid base slab. The tank is filled to an arbitrary depth with an inviscid, incompressible liquid. A finite-element analysis for the free vibrations of the coupled system permits determination of natural frequencies and associated mode shapes. The response of the partially filled tank to artificial earthquake excitation is also determined through use of finite elements. Examples, together with program listing, are offered.
