Transient failure analysis of liquid-filled shells PART II: Applications☆

摘要: Abstract In this paper, applications of the theory developed in companion paper by Liu and Uras [1] are presented. The effects various types ground motion on dynamic stability fluid-structure system analyzed. criteria liquid-filled shells subjected to horizontal rocking excitation, shear loading, bending/shear combined vertically applied load established. resulting instability regions charts given tables ω-ϵ plots. Under motion, modal coupling circumferential direction as well axial is observed. possible buckling modes for a tall tank can be identified cos2θ, cos3θ cos4θ under cos5θ cos6θ, load. For broad two sets found: cos6θ through cos9θ, cos12θ cos14θ motion. When load, failure shift cos10θ cos12θ, cos15θ. effect appears important only if damping relatively small. bending forces dominate fluid-filled shells.
