DESIGN OF SYDNEY OLYMPIC STADIUM FOR MITIGATION OF CROWD-INDUCED VIBRATION
Bibliographic record
Abstract
Increasingly, crowd-induced vibration is seen as an important issue in the design of assembly occupancies, especially large stadia, which are used for pop concerts, involving rhythmic activity, as well as sporting events. This paper presents an overview of an investigation undertaken by Sinclair Knight Merz into the response of the Sydney Olympic Stadium due to crowd-induced vibration. The first part of the investigation involved the construction of a finite element model of the stadium which was subjected to dynamic loading to simulate the likely response of the structure to concert loads. The vibration responses were evaluated in terms of design specifications based on the Canadian Building Code. The results of these simulations, and a review of crowd-induced vibration in the literature, were used to develop the original stadium design to reduce predicted vibration responses. The design approach, together with the final design and its implementation are described in the paper. The second part of the investigation involved the subsequent testing of the structure during a concert performance. Accelerations were recorded at ten locations on the structure over the duration of the concert and the structure was shown to meet the performance requirements for crowd-induced vibration.

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.
