| The research introduces Titanium Alloy Bars (TiABs) for flexural and transverse reinforcing in new bridge piers located in seismic zones. TiABs offer higher strength, good ductility, excellent durability, and enhanced fatigue-resistance compared to traditional reinforcing bars. The research focuses on the applications of TiABs in construction of new bridges located in seismic and corrosive environment. Abridge pier system was introduced that incorporated both seismic resiliency and durability in a single package. Application of TiABs in bridge piers increases service life, reduces rebar congestion, yields to lower overstrength factor, and limits residual displacement following an earthquake. An approximately 1/3rdscale bridge pier reinforced with TiABs rebars and spirals is tested under quasi-static cyclic loading protocol to investigate seismic performance. Results are compared against a benchmark specimen reinforced with normal steel rebars and spirals. The thesis also introduces the available options for splicing of TiABs using mechanical systems to optimize construction costs.
