Modeling and Evaluation of a Seismically Isolated Bridge Using Unbonded Fiber‐Reinforced Elastomeric Isolators
Bibliographic record
Abstract
An unbonded fiber‐reinforced elastomeric isolator (U‐FREI) is a relatively new type of elastomeric bearing that can be implemented as a seismic isolator for bridges. U‐FREIs possess beneficial characteristics, including their potentially low‐cost and light‐weight construction. Individual U‐FREIs can be rapidly produced as they can be easily cut from large sheets to the required size and shape, which is an attractive feature for accelerated bridge construction. The objectives of this paper are to introduce a noniterative analytical model to simulate the lateral response of U‐FREI, and then to utilize the model to investigate the seismic response of a typical highway bridge isolated using U‐FREI and compare it with a traditional non‐isolated bridge. The isolated bridge demonstrated a resilient seismic behavior where all the bridge components remained elastic with no damage or residual deformation. The analytical results indicate that the seismic demand of the isolated bridge is reduced by up to 77% and 84% in terms of base shear and accelerations, respectively, as compared with the non‐isolated bridge.

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.
