Assessment of Seismic Responses of a Base-Isolated Rectangular Fluid Tank with a Bottom Mounted Vertical Baffle under an Irregular Excitation
Bibliographic record
Abstract
The present numerical exploration involves the assessment of the dynamic responses of a partially filled rectangular fluid container decoupled by nonlinear hysteretic bearings.The computational domain exhibits a bottom mounted submerged vertical baffle and is simulated using Galerkin's finite element method based on the velocity potential.The developed model's accuracy is authenticated by comparing with the existing results.The time domain analysis involves a longduration irregular harmonic motion subjected to the system.The findings suggest that the isolation system is remarkably effective across various tank-fluid-baffle setups and efficiently controls key dynamic responses in the fluid tank, including hydrodynamic base shear and sloshing amplitudes.The investigation also evaluates the peak hydrodynamic responses in tanks with and without base isolation, considering different heights and widths of the submerged baffle.It has been found that changes in the h/d ratio have a more significant impact on sloshing amplitude and base shear responses than changes in the w/L ratio.The implementation of base isolation leads to a reduction in sloshing amplitudes ranging from 12% to 34% across different baffle configurations, with the exception being at h/d=0.5.Additionally, base shear is reduced by 2% to 48% in tanks with base isolation, depending on the specific baffle configurations.Notably, the maximum isolator displacement consistently occurs at h/d=0.5, regardless of the baffle width.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
