Abstract
Tuned liquid dampers (TLDs) employ sloshing fluid to reduce the resonant response of structures. Existing structure-TLD models are limited to rectangular or circular tanks, shapes that may not always be feasible in practice due to geometric restrictions of the building floor plan. This paper utilizes an equivalent linearized mechanical model and a nonlinear multimodal model to predict the response of the structure-TLD systems where the TLD tank geometry is irregular. Experimental structure-TLD system tests are conducted that consider two irregular tank shapes. Response history plots and frequency response plots of the structural displacement and TLD wave heights are created to evaluate the models using the experimental results. The parent distributions and 10-minute peak distributions of the structural displacements and TLD wave heights are created for the simulated and experimental results. These distributions indicate that both the linearized and nonlinear models can accurately predict the structural response; however, the linearized model substantially underestimates the peak wave heights. Since wave heights are required to establish the required tank free board, or roof impact pressures, it is concluded that nonlinear analysis of the structure-TLD system model is required before a TLD design is finalized.

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 it
