Well-designed rocking self-centering (RSC) columns are capable of achieving small residual displacement. However, few studies conducted the quantitative analysis for the residual displacement of RSC columns. The residual displacement is the product of the struggle between the self-centering (SC) capacity and the energy dissipation (ED) capacity. In this study, a SC factor and an ED parameter were defined to reflect the SC and ED capacity of the RSC column, respectively. The influence of eight common design parameters on the SC factor and the ED parameter was explored using factorial analysis. Parametric analysis was performed to investigate the tendency of the SC factor and the ED parameter with the increase of maximum drift. According to the results of the parametric analysis, the effect of the SC factor and the ED parameter on the distribution of the residual drift was researched statistically. A simplified formula was proposed to calculate the upper limit of the residual drift. What is more, a set of predictive regression formulas was established to estimate the actual residual drift, these regression formulas have an applicable condition that the ED parameter should be larger than 0.75. When the ED parameter was less than 0.75, the residual drift is approximate to zero.

“…However, in the experiment conducted by Wang et al (2018bWang et al ( , 2019b, mild steel bars passing through the bottom two segments were configured as energy dissipation (ED) devices. Seismic performance of three posttensioned UHPC hollow columns with different axial load ratio (0.018 or 0.036) and diameter of the ED bars (16 mm or 22 mm) was studied.…”

Ultra-high performance concrete (UHPC) is a type of cementitious composite, and demonstrates very high compressive strength and good ductility. The favorable ductility and energy dissipation capacity of UHPC material make it possible to achieve excellent seismic performance in all kinds of structural members. The paper reviewed the recent progress on the seismic behavior of UHPC members, including flexural members (beams and plates), compressive members (columns and shear walls), joints (beam-column joints and plate-column joints), strengthening (strengthening for columns, shear walls and joints) and connections (bar lap splice and grout). A series of potential future researches on the seismic behavior of UHPC members were finally suggested for promotion of the application of UHPC in civil engineering.

“…[15] proposed a methodology to calculate the shear strength of precast-segment concrete piers. Based on the geometric and material symmetry characteristics of precast-segment bridge piers, Wang et al [16,17] established an equivalent plastic hinge model of posttensioning precast-segment ultrahigh-performance concrete bridge columns and discussed the influences of seven related parameters on the energy dissipation and self-centring capacity of the piers. ey proposed a new quantitative design criterion for the selfcentring capacity of precast-segment ultra-high-performance concrete bridge piers and established a fine numerical model.…”

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.
