Sažetak (engleski)

The common corrosion problem in conventional steel reinforcement induces a significant
deterioration of the bridge pier’s yielding displacement and ductility. Superelastic shape memory
alloy (SE-SMA) possesses a high corrosion resistance and retrievers its original shape upon
load removal. The unique material properties attract the attention for structural design use.
However, the yielding displacements of members reinforced with SE-SMA materials required
an investigation to fully understand the material’s effect. In this paper, an extensive parametric
study is performed to estimate the yielding displacement of bridge pier reinforced with SE-SMA
rebars. The parametric study’s size is decided by varying the reinforced concrete (RC) section
characteristics, including axial load ratio, pier diameter, aspect ratio, reinforcement ratio, and
confinement coefficient. Results of this study proposed an approximate formula to estimate the
yielding displacement of SE-SMA bridge piers.
