Damage Progression in Column – Drift Capacity Model Progression of damage in a shear-critical RC column can be quantified using an empirical drift capacity model based on the column’s lateral displacement (i.e. ‘drift’) Drift Ratio at Yielding of Longitudinal Reinforcement (∆/L) Y = 0.00494 Drift Ratio at Shear Failure (∆/L) SH = 0.026248 Drift Ratio at Axial Failure L (∆/L) AX = 0.035183 L
Damage Progression in Column – EPP Backbone Model Elastic-Perfectly-Plastic (EPP) backbone model approximates the shear load vs. lateral displacement behavior of shear-critical RC columns via. a ‘shear-failure surface’ EPP backbone model utilizes the calculated column drift ratios at yielding, shear & axial failure, as well as the yield moment derived from the column moment-curvature response to generate the column’s ‘shear failure surface’ under lateral and gravity loading
