The current research examines the seismic performance of irregular cross-section of bridge piers that has rarely been investigated. Preceded by a successful validation, the study was numerically conducted by ABAQUS/Explicit program containing a comprehensive series of FE bridge piers under unidirectional cyclic loading and axial dead load. Three corrugated shapes with a net depth of 60, 80 and 146 mm mainly formed the cross-sectional configuration of concrete-filled steel bridge piers. The aim was to examine the load-bearing capacity, ductility and buckling mode of such models and compare their behavior with traditional circular-shaped steel columns. Afterwards, a parametric study involved the grade of concrete (20, 30, and 40 MPa), corrugation geometry (C60, C80, and C146 mm), radius-to-thickness ratio (0.131, 0.149, and 0.116), and axial force ratio (10%, 15%, 20% and 30%). FE results suggested that concrete-filled corrugated-shaped columns revealed nearly 50% more load-bearing capacity and ductility as compared to circular-section columns. The damage configuration among corrugated-shaped columns was seen less severe than circular-section columns, where the local buckling in the latter one was premature and concentrated in particular zone. The findings herein urge to consider implementing corrugated-shaped piers in structures due to their significant addition in strength, ductility, and failure control.
