Thin-Walled Hollow Steel Box Piers with Energy Dissipation Mechanism Under Bi-directional Cyclic Loading
The seismic design of bridge piers is often conducted using horizontal dynamic analysis employing several orthogonal directional seismic acceleration data. This simplistic treatment, however, does not account for the effect of complex earthquake loading as a structural response to inelastic interactions. This study explores the hysteretic behaviour of a proposed thin-walled steel square box column with an energy dissipation mechanism under constant axial force and linear and non-linear cyclic lateral loading. First, the adopted finite element model (FEM) in ABAQUS is validated with experimental results from the published research and then used for analysis. Then, several linear and non-linear idealised loading patterns are used to evaluate the strength and ductility of the proposed and standard columns. In addition, the failure mechanisms of each proposed column were explored for specified loading patterns.
