“…Nazari et al [61] stated that the energy dissipated due to rocking was ignored in previous experimental studies because they were conducted primarily using quasi-static loading, and increasing the ASR would result in higher ED. However, comparison of single rocking walls designated as SRW-A tested by Twigden and Henry [73] on a shake table and SRW-B tested by Twigden et al [62] using quasi-static load indicates that changing load on the wall from quasi-static to dynamic load leads to a decrease in EVD. SRW-B test reported 4.7% EVD at 2% drift, and SRW-A had 3.62% EVD on average.…”

The application of unbonded post-tensioning (PT) in structural walls has led to the development of advanced self-centring (rocking) shear wall systems that has significant advantages, including accelerated construction due to the incorporation of prefabricated elements and segmental construction for different materials (e.g., concrete, masonry, and timber), reduced residual drifts, and little damage upon extreme seismic and wind loads. Concrete, masonry, and timber are often used for the construction of unbonded PT structural wall systems. Despite extensive research since the 1980s, there are no well-established design guidelines available on the shear wall configuration with the required energy dissipation system, joint’s locations and acceptance criteria for shear sliding, confinement, seismic performance factors, PT loss, PT force range and residual drifts of shear walls subjected to lateral loads. In this research a comprehensive state-of-the-art literature review was performed on self-centring shear wall system. An extensive study was carried out to collect a database of 100 concrete, masonry, and self-centring shear wall tests from the literature. The established database was then used to review shear walls’ configurations, material, and components to benchmark requirements applicable for design purposes. The behaviour of concrete, masonry and timber shear walls were compared and critically analysed. The general behaviour, force-displacement performance of the walls, ductility, and seismic response factors, were critically reviewed and analysed for different self-centring wall systems to understand the effect of different parameters including configurations of the walls, material used for construction of the wall (concrete, masonry, timber) and axial stress ratio. The outcome of this research can be used to better understand the behaviour of self-centring wall system in order to develop design guidelines for such walls.

“…Even though R = 6 or 7 is used for the design of self-centering structural systems using the force-based design method (Smith et al [22], Buddika and Wijeyewickrema [24]), a wide range of R values are adopted in this study. This is done so that the developed FRS in Section 4 can also be used with the direct displacement-based design method, where the R value depends on the target displacement (Priestley et al [26], Yang and Lu [27]). It is noted that for SC flag-shaped SDOF systems, a viscous damping ratio ξ p = 5% has been used in previous studies (see for e.g., Rahgozar et al [28], Zhang et al [29], Dong et al [30]).…”

Spectral floor-acceleration demands are necessary for the seismic design of acceleration-sensitive non-structural components (NSCs). Existing studies to estimate floor response spectra (FRS) using empirical equations are based on elasto-plastic and stiffness degrading hysteretic behavior of the primary structure. In the present study, the FRS for self-centering (SC) structural systems with flag-shaped hysteretic behavior under far-fault ground motions are investigated. The FRS and dynamic amplification factor (DAF) are obtained from nonlinear response history analysis (NLRHA) of SC structural systems with flag-shaped hysteretic behavior. An equation to estimate the FRS is proposed and verified by carrying out NLRHA using a different set of far-fault ground motions. The equation to estimate FRS is shown to predict floor acceleration demands with very good accuracy.

Recycled aggregate concrete-filled square steel tube (S-RACFST) frame has the characteristics of high bearing capacity, good ductility, and superior seismic performance. To propose a displacement-based seismic design of S-RACFST frame, the validity of the design method was verified by a detailed calculation example. Based on the performance requirements, this design method divided the structural performance into five levels: normal use, temporary use, use after strengthening, life safety, and collapse prevention, and suggested specific steps for the displacement-based seismic design of S-RACFST frame using the inter-story displacement angle limit value as the quantitative indicator. The 10-story S-RACFST frame was used as an analytical example for static elasticplastic analysis. The pushover lateral displacement curves of the frame structure at each performance level were obtained and compared with the displacement-based seismic design curves. The results show that the displacement-based seismic design method of S-RACFST frame structures can fulfill the performance level requirements such as "temporary use," "normal use," and "collapse prevention," and the displacement-based seismic design method is one of the effective ways to realize the performance design of S-RACFST frame structures.
