Seismic Behavior of Severe Damaged GFRP Tubed RC Bridge Piers Repaired with CFRP

Abstract:

In order to investigate the seismic behavior of earthquake-damaged glass fiber reinforced polymer (GFRP) tubed reinforced concrete(RC) bridge piers repaired with wrapped carbon fiber reinforced polymer (CFRP) sheets. An experimental study, in which four GFRP tubed RC bridge piers repaired with wrapped CFRP sheets were tested under constant axial load and cyclic lateral displacement excursions that simulated seismic force,are presented in this study. Researches show that repaired with CFRP not only increase bridge piers’ultimate strength but also improve the performance such as ductility.
