Abstract

Seismic response of liquid sloshing in horizontally baffled rectangular container on deformable ground is evaluated. An equivalent mechanical model of baffled sloshing is developed. The strip partition method is presented to analytically derive the foundation impedances reproduced by nested lumped-parameter model. The system equations of motion are constructed via applying Hamilton’s principle. The detailed validations are performed against the available solutions. Effects of soil and baffle parameters on surface wave elevation and base loads under three earthquake records with different frequency contents are examined. Results highlight that seismic behaviors of baffled container have a high sensitivity to earthquake frequency content.
