Structural analysis of transmission towers with connection slip modeling
Bibliographic record
Abstract
In an effort to improve the structural analysis of transmission towers, this study investigates the effect of bolt slippage on the deflections and member stresses of latticed self-supporting transmission towers. The computer program developed in this study can model tower members as truss and beam elements, can incorporate bolt slippage using an instantaneous slippage model or a continuous slippage model, and can model the connections as semi-rigid (flexible connections) provided moment-rotation data are available. The slippage models require certain parameters, determined from load deformation experiments on typical angle members, in order to accurately incorporate the effect of bolt slippage. Each member of the transmission tower can have its own slippage properties (most importantly the actual amount of clearance slip and the load which initiates clearance slip) depending on its size and connection configuration. The slippage models are applied to several structural analysis problems: a simple one-dimensional bar element, a double-diagonal plane truss, a double-diagonal plane frame with semi-rigid connections, a simple three-dimensional transmission tower, and a full-scale transmission tower.

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.
