“…This suggested that increasing reinforcement beyond 1.83% did not increase toe compressive capacity due to lower effect of confinement on the compressive strength at a very large reinforcement ratio. Holden et al [59] and Gu et al [57] made similar observations. Smith and Kurama [60] reported that misalignment of the confinement hoops could also be responsible for premature failure of the wall base used a 1.87% volumetric confinement reinforcement ratio, and no premature failure at wall toe was reported.…”

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.

To reduce the damage to reinforced concrete shear walls in earthquakes and repair costs, a self-centering wall with sloped plane friction dampers (SPFDs) is proposed. In addition to the SPFDs, the proposed wall includes a precast composite wall, steel wall toes, and post-tensioned (PT) tendons. The steel wall toes embedded in the base of the precast wall were used to improve its strength, and the SPFDs installed in the steel toes were used to increase its energy dissipation capacity. To investigate the effect of the initial PT force and prestressing clamping force of the friction bolt on the seismic performance of the wall, quasistatic cyclic loading tests were carried out on three precast wall specimens. The damage to the self-centering walls was slight, the residual drift was small, and the energy dissipation met the specification requirements. The wall with the greater initial PT force showed higher self-centering and bearing capacity, and the wall with higher prestressing clamping forces showed greater energy dissipation capacity. Additionally, a calculation method for the bearing capacity of the precast wall, which was verified by comparison with the test results, is suggested.

“…Precast concrete (PC) offers good potential to replace cast-in-place concrete in building construction owing to its high-quality structural members, short construction period and low labour to produce (Li et al, 2020; Zheng and Zheng, 2020; Wang et al, 2020). In general, connections between PC components can be divided into two types: “wet connections” and “dry connections”.…”

“…PC structures with wet connections have comparable structural performance to castin-place concrete structures. Thus, they were also named monolithic PC structures (Li et al, 2019(Li et al, , 2020Xu et al, 2017;Zhi et al, 2017;Gu et al, 2019;Mostafa et al, 2021;Zheng et al, 2020;Deng et al, 2020;Zhang et al, 2020). However, wet connections have some disadvantages.…”

An innovative shoe bolt connection for precast concrete (PC) structures that features resilience is proposed in this study. In this connection, a steel washer plate that could be easily replaced after an earthquake serves as the “fuse” element, and the bolt passing through the horizontal joints serves as the self-centring element. To validate the reliability of the proposed connection, quasi-static tests were conducted on two PC shear wall specimens. One specimen was designed with a conventional wall shoe bolt connection (S-1). The other specimen was designed with the proposed connection (S-2). The crack pattern, failure mode, hysteresis curve, skeleton curve, ductility and energy dissipation capacity of the specimens were studied. Furthermore, finite element (FE) analysis was conducted to reproduce the test and facilitate an in-depth understanding on the mechanism of the specimens. The test and analysis results indicated that S-1 exhibited brittle failure, while the failure of S-2 was governed by concrete crushing and fuse plate yielding and reflected a remarkable self-centring capacity; only minor shear slips of the horizontal joints occurred, even for the specimen S-1 with a smaller axial load ratio, indicating that the joints had enough shear resistance; the proposed three-dimensional FE model could predict the skeleton curve and the failure mode of the specimens with acceptable accuracy; for the specimen with proposed connection, the failure mode was significantly influenced by the thickness of the fuse plate.
