Abstract
Resilience and recoverability play important roles in controlling the structural performance of reinforced concrete (RC) structures after seismic actions. The main objective of this paper was to propose a new earthquake resistant method using a near surface mounted basalt fiber reinforced polymer rods (BFRPR-NSM) to minimize residual displacements, and to execute a fiber model based simulation evaluating the structural performance of the proposed BFRPR-NSM method reinforced RC columns. Based on the experimental results on both existing RC bridge columns and newly constructed columns, the beneficial effects of the BFRPR-NSM method were discussed. Moreover, the analytical studies on post-yield stiffness and residual deformations of BFRPR-NSM reinforced columns were conducted. Finally, suitable FRP design assumptions and concepts certifying the reality of post-yield stiffness are given.
