Towards Damage-Based Design Approach for RC Bridge Columns under Combined Loadings using Damage Index Models
Abstract
This article investigates a damage-Based design approach for circular reinforced concrete (RC) columns under combined bending, shear, and torsion using decoupled damage index models. the combination of bending moment, shear, axial, and torsional loading affects the structural performance of bridge columns with respect to strength, deformation capacity and progression of damage. the damage index model proposed here permits decoupling these combined actions according to various damage limit states. This work evaluates the interaction between bending and torsional damage indices in terms of progression of damage. It also investigates the effects of the transverse reinforcement ratios and shear span. based on experimental and analytical results increase of torsion amplified the progression of damage. the increase in transverse reinforcement ratio was found to have delayed the progression of damage and to have changed the torsional dominated behavior to flexural dominated behavior under combined bending and torsion.
