Abstract:

Under an extreme ground motion excitation, the flexural capacity of a well-designed reinforced concrete (RC) column deteriorates due to significant damage to the plastic hinge. Plastic hinge damage includes spalling of concrete cover, buckling and rupture of longitudinal bars, and concrete core crushing. Thus, it is important to prevent damage at the plastic hinge region for developing "seismic resistant" columns. This paper presents a bilateral cyclic loading experimental investigation of bridge columns having plastic hinges consisted of ultra-high performance steel fibre concrete (UFC). Two columns having different plastic hinges details were investigated using bilateral cyclic loading; one column had reinforced concrete core encased in UFC jacket and the other column had UFC hollow-core plastic hinge combined with post-tensioning. Both columns were designed to have approximately the same nominal strength. The columns were constructed and tested at Tokyo institute of Technology in Japan using orbital bilateral cyclic loading customized to impose flexural deformations along with investigating the possibility of twisting of the columns. The column having solid concrete core was able to carry the applied axial load until a drift of 6% whereas the post-tensioned column was able to carry the applied axial load until a drift of 3.5%. The seismic performance of the column with concrete core is clarified based on a hybrid loading experiment.
