Abstract

In order to study seismic performance of FRP confined RC hollow section bridge pier, quasi-static test was carried out for CFRP confined RC rectangular hollow section bridge pier with shear-span ration of 4 and 8 under horizontal unidirectional and bidirectional loads.Failure mode, hysteretic curves, lateral force and displacement of tested pier columns were analyzed respectively.The results show that through confining plastic hinge region of tested hollow bridge pier by CFRP, the failure location and damage degree are reduced, and the failure mode of tested bridge piers with lower shear-span ratio is changed;the hysteretic performance and ductility of tested bridge piers with bigger shear-span ratio are improved, however, horizontal force is only increased by less than 20%.
