Abstract

Abstract: The low-cyclic reversed loading test was carried out for a scale model of a neotype column-slab high pier. The test was designed to investigate its failure modes, hysteretic characteristics, ductility, energy dissipation, residual deformation stiffness degradation. Test results indicate that the neotype column-slab high pier has strong and stable bearing capacity, good ductility and energy dissipation capacity, small residual deformation. The destruction process of the structure components is that bending cracking of the wing slab buttom firstly, shear cracking at the juction of the web plates with the corner columns, then bending cracking at the roots of the corner columns. Cracking and energy dissipation of the slabs decrease the stiffness of the structure, which effectively protects the corner columns. The study contributes to the literature for developing future design guidelines, for the purpose of providing experimental and theoretical background of the neotype column-slab high pier.
