Abstract

This study investigates the confinement effect of polypropylene fiber reinforced cement composites (PFRC). The study utilized the experimental results of Zhang et al. (2013) on "Effect of Tie Bar Volume on the Seismic Performance of Polypropylene Fiber Reinforced Columns based on Hybrid Loading Experiments". Two 6/35 scaled bridge pier models having PFRC material at its plastic hinge region were identical except for the spacing of transverse reinforcement. The pier models were subjected to hybrid loading where measured displacement at the JR Takatori Station during the 1995 Hyogoken-nanbu Earthquake were used as input displacement. Through the analysis of measured longitudinal and tie strains of two models, it was shown that at certain levels of excitation, strains of the reinforcing bars are similar on both models. Strains of outer and inner transverse bars within the plastic hinge region are still in the elastic stage at the end of 25% excitation. Moreover, through the comparison of observed damages of models, it was shown that concrete cracking and concrete cover spalling were minimized due to the damage mitigation properly of PFRC.
