Effects of Connector Modelling on Explicit Shell Finite Element Models of Cold-formed Steel Shear Walls
Bibliographic record
Abstract
The study presented herein is concerned with assessing the influence of connector elements on the behaviour of finite element models of high capacity cold-formed steel (CFS) shear walls.Recently, CFS shear walls have been used as an economic and light-weight seismic force resisting system (SFRS) in North America, however their applications are limited to mid-rise buildings.To push the state-of-the art, a preliminary testing programme of an innovative, higher-capacity CFS shear wall is conducted.The testing programme consists of monotonic and cyclic tests as well as screw connection assembly tests in double shear.Furthermore, explicit shell finite element models of the shear walls were developed and calibrated with the experimental results.Finally, a parametric study on the type of connector element was carried out to assess the behaviour of the wall.The results indicate that representing the screw-fastened connections using three uncoupled springs gave the best numerical estimate.

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.
