Backbone Model & Deformation Classification for Extended Endplate Connections

🌙

Lengths in mm, stresses in MPa. Column and beam sections come from your Database_Sections table; bolt sizes from your Database_Bolts table. f_u for the column, f_y for the beam, and f_y for the bolt are shown for reference — the models don't use them. To use a different section table: Load section table (.csv)

* For a cyclic backbone, the strength parameters should be amplified by 10-15% to account for cyclic hardening.

Random Forest deformation-mode classifier

Based on a 95-tree Random Forest exported from Get_Classification_RF.mat (Ding & Elkady, 2025). Hard-vote share across trees is shown as the probability for each mode.
