Seismic Design Method of Self-Centring-Segment Bridge Piers with Tensile-Type Viscoelastic Dampers

This paper aims to study the deformational behaviour of tensile‐type viscoelastic dampers under different earthquake excitation directions. A method for calculating the corresponding equivalent additional stiffness and damping of a self‐centring‐segment bridge pier is derived. Using the displacement‐based seismic design method, a design method for self‐centring‐segment bridge piers with tensile‐type viscoelastic dampers is proposed. Using the proposed method, a self‐centring‐segment bridge pier is designed. Based on dynamic analysis of the finite element model by OpenSees, the effectiveness of the proposed seismic design method is validated.
