Experimental Study on Seismic Performance of CFRP Confined RC Rectangular Hollow Section Bridge Piers
To investigate the seismic performance of fiber-reinforced polymer (FRP) jacketing constrained reinforcement concrete (RC) hollow section bridge piers under multi-dimensional earthquake action, cyclic tests of five RC rectangular hollow section benchmark and carbon fiber reinforced polymer (CFRP) jacketing confined piers specimens were carried out under unidirectional and bidirectional lateral horizontal repeated loading. The failure characteristics, lateral force-deformation curves, effective loading stiffness, ductility and energy dissipation of specimens were analyzed. The experimental and analytical results show that: the damage is more severe; the failure process is accelerated; and bearing capacity, ductility, rigidity and energy dissipation are decreased under bidirectional earthquake action. The CFRP constraints may: change the failure location and mode of bridge piers; improve the deformation ductility, plastic deformation and energy dissipation, but have less contribution to horizontal force.
