Abstract

fetched live from OpenAlex

<p>In the context of the Northern Marmara Motorway Section 8 Project, a new cable-stayed bridge, the Sazlidere Bridge, is being designed and works have already started on site. To support this fast-paced project, RWDI is collaborating with the design team and providing wind engineering services. The activities employ wind tunnel experiments and are focused on two main aspects: aerodynamic stability of the bridge and the risk of wind-induced overturning of large lorries crossing the bridge. With respect to aerodynamic stability, limited tests on a sectional model of the bridge deck were performed in one of RWDI’s wind tunnels using a state-of-the-art sectional model test rig. Testing of a full bridge aeroelastic model with relevant topography was also conducted allowing for the simulation of atmospheric turbulence from any wind direction. This testing was used primarily to verify the aerodynamic stability of the structure for various wind directions and to measure the buffeting response of the bridge to turbulent winds. Further wind tunnel testing on a small-scale rigid transport lorry model was completed to measure the aerodynamic force and moment coefficients of the vehicle as a function of wind direction. These data were combined with a numerical model for the roll-over stability of high-sided vehicles to calculate critical wind speeds versus wind direction for lorries driving along the central span of the bridge.</p>

Teacher imitation

Not 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.
