Abstract:
This paper investigates the seismic performance of a novel member with UHPC, FRP, and stainless-steel materials under simulated cyclic loading and earthquake ground motions. The member is composed of an FRP shell and a UHPC core reinforced by stainless-steel rebars, which boosts a significant advantage to resist corrosion as compared to reinforced concrete. The member’s cyclic behavior is simulated using OpenSees with three other members in different material/structural configuration. The results demonstrate that the proposed member has the best seismic performance in strength, stiffness, and energy dissipation. Subsequently, a parametric study is performed to investigate cyclic behavior based on different material properties and structural configurations. Finally, the member’s seismic performance is studied under earthquake ground motions. The analytical results exhibit a promising application of the novel member for a resilient, durable, and corrosion-free civil infrastructure.
