“…This type of study is resource-intensive due to the extent of the NLTH analyses required. Therefore, many newly developed structural systems, such as self-centring rocking walls, do not have well-established seismic response factors in building codes [2]. Questions remain on how to solve period-stiffness dependency, provide simple design equations, and proceed in cases of hybrid systems with subsystems characterised by different plastic behaviour [23].…”

“…These structures show limited residual deformation upon loading events such as earthquakes which are repairable with minimal cost [1]. The controlled joint opening also helps the wall to provide a higher ductility which results in a reduced shear and flexural demand on the wall due to seismic loads [2]. Rocking shear walls accommodate displacement ductility demands by allowing for a concentrated gap to open between the wall and foundation interface instead of allowing for the development of plastic hinges as in shear walls with monolithic (fixed based) connection [3].…”

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 further improve the seismic performance and reduce the cost of post-disaster reconstruction, components with a high energy dissipation capacity and that can be easily replaced when damaged have begun to be installed in steel frame structures [7][8][9][10][11][12][13][14][15][16][17].…”

To improve the seismic performance of steel frame buildings in rural areas, an energy-dissipating composite wall (EDCW) assembled from concrete-filled steel tubular columns and concrete sheet walls was designed. Cyclic loading tests were simulated using the finite element method (FEM) to analyse the seismic performance of the EDCW. The reliability of numerical modelling and analysis was verified by comparing the hysteretic curves obtained by the finite element model with those obtained by previous experiments. The EDCW was designed for installation in a two-storey steel frame, and the FEM was used to determine the seismic performance of the steel frame, including the deformation and failure characteristics, hysteresis curves, and skeleton curves. The numerical simulation results showed that the EDCW dissipated most of the seismic energy and thus substantially improved the seismic performance of the frame. The seismic performances of 16 frames were compared to investigate the effects of the span ratio of the steel frame to the EDCW, the installation location of the EDCW, and the stiffness of the steel frame on the seismic performance of the frame.

“…[ 13–16 ] Also, several shake table tests have been carried out on the precast concrete buildings with hybrid wall system. [ 17,18 ] The results show that the hybrid wall system has an ideal flag‐shaped hysteretic behavior, representing superior self‐centering ability and enough energy dissipation capacity. However, it should be kept in mind that the use of internally mild steel bars leads to impossible inspection and irreparability for the system.…”

Summary By proposing a multiple rocking infill wall–frame (MRWF) system, this paper investigates the effects of wall–frame interaction on the seismic response of self‐centering walls. In the MRWF system, infill walls are connected to the adjacent beams through posttensioned tendons, which provide the self‐centering ability, and the energy dissipation capacity of the system is enhanced using O‐shaped steel dampers. The seismic behavior of the MRWF system, with various wall configurations, is evaluated alongside conventional shear wall and typical rocking wall systems at three height levels of two, four, and six stories. After developing the numerical models, the cyclic and time history analyses are carried out. The results of cyclic analysis show that the energy dissipation capacity of MRWF models is much higher than that of typical rocking wall models. Furthermore, for the MRWF models, by increasing the number of walls with a smaller width, the effect of wall–frame interaction is mitigated, resulting in minimal damage to the structural members and self‐centering ability of more than 90%. The time history analysis results illustrate that for the MRWF models, the residual drifts and plastic rotation at the beams are significantly reduced by applying the proper structural layout of the multiple rocking walls, especially for six‐story models.
