Abstract:Circular, spirally reinforced concrete bridge columns were subjected to cyclic inelastic lateral loading in the laboratory. The bridge columns were 1/6-scale models of prototype columns designed in accordance with recent California Department of Transportation specifications. A total of six models were tested. Three of the models were constructed with microconcrete, and three were constructed with ready-mixed concrete using pea gravel. Variables included the aspect ratio, magnitude of axial load, and the type of material. The models were subjected to slow reversed cyclic lateral displacement with the axial load held constant. Results from the tests are presented in the form of load-displacement curves and energy absorption plots.
