 Abstract
Scaled model tests were carried out to investigate a seismic behavior of reinforced concrete piers with hollow-rectangular section that were not detailed for seismic load. Additional lateral reinforcing bars were not provided that might be required for confinement against earthquake load. Two kinds of reinforcement details were considered for the longitudinal reinforcing bars: lap-spliced and continuous. In the lap-spliced model all longitudinal bars were lapped at the same height in a bottom plastic hinge zone. In the other model all longitudinal bars extended continuously throughout the height. The constructed models were subjected to quasi-static cyclic lateral loading in the presence of the constant vertical load. Limited ductile behavior was observed in the test of lap-spliced model and more ductile behavior was observed in the test of a continuous longitudinal reinforcement model.
