• Abstract:
  The properties of UHPC make it a suitable choice as the repair material for retrofitting the damaged body of the marine piles, and application of UHPC could provide an efficient solution to address the pressing issue of bridge rehabilitation. However, there have been very limited studies investigating the feasibility of using this material to repair concrete columns. This research aims to investigate the performance of UHPC as retrofit material for damaged bridge columns. To achieve this goal, an experimental study was designed to evaluate the mechanical performance of the repaired columns under a combination of static axial and cyclic lateral loads (to simulate operational conditions). In the rest of this article, Section 2 explains the column construction, artificial damage and repair, test setup, and instrumentation procedures; Section 3 outlines test observations and results; and Section 5 presents the concluding remarks.
