Several techniques are available to repair these structures to meet the increasing demand and enhance their safety. This thesis investigates the effectiveness of a glass fiber reinforced polymer (GFRP)-based system for rapid repair of buckled steel piles. The system consists of a GFRP tube, which is formed on-site and subsequently filled with an expansive concrete. Thirteen-buckled steel H-piles with varying degrees of section loss to simulate corrosion were repaired and tested to failure under axial loading. The research results show that the repair system can restore the capacity of the piles comparable to the undamaged conditions.application/pdfengThe author of this work is the copyright owner.
