Bond behavior of the reinforcement bar in GFRP connector

Abstract

This paper presents the bond stress -slip behavior of a newly developed grouted splice connection fabricated by glass fiber-reinforced polymer (GFRP). A total of twenty seven specimens were tested under increasing axial tension load. Results from the test specimens were adapted to model a bond stress -slip law to be compared with the requirements provided by design codes and provisions. The results show that by reducing mid-length diameter, higher bond strength and load capacity are generated in the tapered splice sleeves.
