EXPERIMENT CONCERNING THE REINFORCEMENT OF THE STEEL PILES HEAD OF OPEN-TYPE WHARF BY JACKETING UHP-SHCC

Abstract

 In this paper, the authors have developed a new protective covering system which can ensure the anticorrosion of steel piles and strengthening of joint parts between steel pile and beams of the concrete superstructure by applying the Ultra High Performance-Strain Hardening Cementations composites, UHP-SHCC, which is one of the fiber reinforcement mortars using the synthetic short fibers. The authors evaluate the effect of the improvement of flexural capacity of the steel piles and joint parts between a steel pile and a beam of a superstructure. The large scale flexural loading tests of tested steel piles, to which the UHP-SHCC protective covering system was applied, were performed in the laboratory.
 From the loading test and discussions, the authors confirmed that the UHP-SHCC protective covering system efficiently contributed to improvement the flexural capacity.
