Performance of a seismic-resilient precast segmental column with UHPC segments and CFRP tendon

Seismic fragility analysis of high‐strength concrete frame structures reinforced with high‐strength steel bars

“…3 Therefore, many researchers are committed to developing the resilient engineering structures using a type of self-centering reinforcement featuring higher tensile strength and lower bond stress, such as shape memory alloy (SMA) bars, fiber reinforced polymer (FRP) bars, or high-strength steel strands. 4,5 Sun et al, 6 Yuan et al, 7 Cai et al, 8,9 and Li et al 10 conducted a series of cyclic loading tests on concrete columns reinforced with hybrid steel/FRP bars, which showed that these innovative columns exhibited higher postyield stiffness and smaller residual deformation compared to ordinary RC columns. In addition, a novel reinforcement of steel-FRP composite bar combining the advantages of the steel bar and FRP has also been proposed to obtain better resilience.…”
