Optimal design and performance of inter-story isolation system with inerter damper considering soil–structure interaction under near-fault pulse-like ground motions
Bibliographic record
Abstract
The study investigates the optimal seismic performance of inter-story isolation system (IIS) with tuned inerter damper (TID) and tuned mass damper inerter (TMDI), considering soil–structure interaction. Simplified 6-degree-of-freedom models for two control systems are developed to analyze the seismic response variations of the systems under stationary white noise excitation. Frequency and damping parameters are optimized based on objective functions related to displacement and acceleration. The analysis also explores the effects of model parameters on optimum design. A comparison is made between the seismic responses of IIS with and without TID/TMDI under 34 near-fault pulse-like ground motions (NPGMs) through time history analysis. The results demonstrate that TID and TMDI effectively control acceleration and displacement responses of the systems. Notably, NPGM characteristics significantly influence control effectiveness, which should be carefully considered in design. It is highlighted that this optimal design strategy is applicable across various soil conditions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
