The characteristics of titanium reinforcement,
particularly its ability to be bent, open up possible cost savings for a wide
range of strengthening situations. Three
areas have been identified for further
research to exploit the advantages of titanium reinforcement for strengthening:
• Develop a splicing method that allows supplemental reinforcing bars to be deployed along the full length of girders including through the intermediate diaphragms that protrude from most beams.
• Develop an unbonded strengthening detail that eliminates the need to cut grooves into the concrete surface, thereby reducing labor costs, epoxy material costs, and construction time.
• Develop methods to apply exterior titanium bars to strengthen girders with inadequate transverse reinforcement.
