“…Additionally, severe prestress loss was discovered in a fully prestressed column (FPC). Moreover, STTs have been performed to investigate the dynamic response of the columns (Ge and Wang, 2011; Mantawy et al, 2016; Ou et al, 2018; Li et al, 2019a). After experiments, the column showed significant flexural cracking at the bottom joints.…”

“…To understand the seismic performance, QSCTs have been performed by some scholars (Palermo et al, 2007; Ou et al, 2010; Bu et al, 2016). After QSCTs were conducted by Ou et al (2018), the column exhibited high ductility and high energy dissipation. A precast column with UPTs and high-strength ED bars was tested by Tong et al (2019), and the results revealed good ductile behavior, satisfactory energy dissipation, and SCC.…”

“…Recently, several researchers have introduced additional components with the rocking connections to accelerate the construction process or to improve the seismic performance. These components include: external energy dissipation) ED) devices as shown in Figure 5 (Jia et al, 2020;Jia et al, 2022;Ou et al, 2010;Ou et al, 2018) 2021) introduced column to footing pipe connection as shown in Figure 5(f). Emerging type connections with posttension tendons have been presented by (Motaref et al, 2014;Ou et al, 2013;Zhang et al, 2019), as shown in Figure 5(m) and (n).…”

“…In order to shorten the construction period, reduce the impact of the bridge construction process on traffic and the surrounding environment, and facilitate the construction of bridges under complex conditions such as sea and mountainous areas, the precast segment assembly method as shown in Figure 1(a) for accelerated bridge construction has attracted increasing attention in recent decades (Billington et al, 1999; Bu et al, 2016; Cai et al, 2021; Jia et al, 2020; Li et al, 2019; Mashal and Palermo, 2019; Ou et al, 2018). Meanwhile, to prevent the bridge columns from being demolished due to excessive residual deformation after an earthquake (Kawashima et al, 1998), unbonded post-tensioned prestressing tendons (UPPTs) applied to the precast segmental bridge columns (PSBCs) have been extensively studied to improve their self-centering ability (Chou and Chen, 2006; Guerrini et al, 2015; Hewes, 2007; Ichikawa et al, 2016; Marriott et al, 2009; Shen et al, 2021; Wang et al, 2018b; Zhang et al, 2021).…”
