A Shape Memory Alloy-Pendulum Damping System for Small Wild Goose Pagoda in Xi’an, China
Bibliographic record
Abstract
This paper aims to develop a system to control the vibrations of ancient pagodas without damaging their original appearance. Taking the Small Wild Goose (SWG) Pagoda (Xi'an, Shaanxi Province) as the target structure, the authors designed a shape memory alloypendulum damping system (SMA-PDS) based on the theory of pendulum damping and the super elasticity of the SMA. To verify the effect of the SMA-PDS, a 1:10 scale model was created for the SWG Pagoda, and subjected to shaking table tests with and without the SMA-PDS. The test results indicate that: the small and flexible system can be installed easily inside the pagoda to dampen seismic vibrations; the SMA-PDS greatly reduced the acceleration response at the top of the SWG Pagoda model; the reduction is particularly prominent (32.5%), when the SMA wires had a pre-strain of 3%; the SMA-PDS worked better in medium and large earthquakes than in small earthquakes. To sum up, this paper provides a novel damping system for seismic vibration in ancient pagodas, shedding new light on the energy dissipation, vibration control and reinforcement of similar ancient pagodas.

How this classification was reachedexpand
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.
