Stability of Bridge Column Rebar Cages During Construction

The lateral behavior and stability of bridge column rebar cages were investigated to reduce the potential of failure and collapse during construction. Two full-scale bridge column rebar cages were subjected to incremental loading to determine the lateral behavior, identify failure modes, and calibrate the analytical models. Using the results from the experimental study, nonlinear finite element analyses were developed to determine the effect of critical parameters on the lateral behavior of column rebar cages. The investigated parameters were: tie wire connections, internal braces, column diameter, longitudinal and transverse reinforcement ratios, and column height. The results of these analyses showed that the internal braces have a significant effect on the lateral behavior and failure mode of bridge column rebar cages. Guidelines for determining the lateral stiffness and improving the bridge column rebar cage stability are proposed.
