“…The reasonable setting of damper activation force and slotted hole length could reduce the damage to the shear wall systems under earthquake action. Cui et al [93] conducted analysis and tests to verify the self-centering mechanism of the systems and demonstrated that the systems could withstand large inter-story displacements, and no plastic zone was formed in steel frame members. Dong et al [94] proposed a slip-frictional damper connection with a lock-up system between walls and frames and established a numerical model to further investigate the influence of wall-to-frame stiffness ratios on the lateral performance for shear walls.…”

Wood is a green material in line with the sustainable development strategy. From the excellent performance of engineering wood products, modern wood structures represented by light wood structures have gained more development opportunities. As an indispensable part of light wood structure systems, the wood-frame shear wall plays a vital role in the bearing capacity and earthquake resistance of light wood structure systems. This paper is focused on a review of the lateral performance of wood-frame shear walls and classifies the influencing factors in relevant experimental research into three categories, including internal factors such as shear wall structure, external factors such as test scheme, and other factors of material production and test process. Finally, the research prospects in this field were introduced based on the summary of the research status. This work can be a reference for further research on the lateral performance of wood-frame shear walls.

“…Instead of relying on PT, Loo et al (2014) introduced rocking in traditional wood shear walls through slip friction connectors replacing steel bracket hold-downs, and Hashemi et al (2018b) expanded on this concept by introducing a self-centering mechanism into the slip-friction connector. More recently, Cui et al (2020) and Li et al (2021) introduced rocking in steel–timber hybrid shear wall systems to improve the seismic performance of multistory timber-based hybrid building structures.…”

This state-of-the-art review provides an overview of the evolution of self-centering structures from early historical structures that inherently exhibited a recentering response to modern systems engineered for enhanced seismic resilience. From the early research investigations that were conducted since the 1960s, to the sharp increase of interest in this topic over the last two decades, self-centering seismic-resistant structures that can mitigate both damage and residual drifts following major earthquakes have seen significant advances. These systems achieve the intended self-centering response by either allowing for the rocking of primary structural elements in a controlled manner, commonly coupled with mechanical restraints and energy dissipation devices, or by including self-centering devices as main structural or supplemental structural members. To better explain the concepts and the underlying mechanics governing their seismic response, detailed schematic illustrations were developed in this article, highlighting the fundamentals behind each of these systems. This article covers a historical overview, presents the state of the research and of the art, discusses general design challenges and practical considerations, and concludes with future research needs to advance the development and broader application of self-centering systems in real structures.

“…Differing from other common friction‐damped systems, [ 10,11,32 ] the slip friction force is provided by two friction interfaces on each side of the beam: one is the MP–IP interface and the other is the MP–EP interface. As mentioned previously, sliding in the VFED can be divided into two stages.…”

Summary A new unbonded post‐tensioned precast concrete (PTPC) frame with controllable post‐decompression stiffness (CPDS), achieved by employing novel variable friction energy dissipaters (VFEDs), is proposed in this paper. A steel corbel (SC) is used in the CPDS‐PTPC connection to enhance the shear capacity. The VFED incorporates grooved steel plates and a combination of Bellville washers to provide variable energy dissipation and load‐resisting capacity to achieve target structural performance at different seismic intensity levels. A series of cyclic tests of a full‐scale beam‐to‐column specimen were carried out with different design parameters to investigate the hysteretic behavior of the proposed CPDS‐PTPC connection. The specimen was subjected to cyclic loading up to 9.0% drift to observe different levels of structural damage. Finally, a numerical model is proposed and validated with experimental data, and parametric analyses were performed by varying geometric properties of the VFEDs in the model. Both experimental and numerical analyses confirm the unique capabilities of the proposed CPDS‐PTPC connections to achieve tunable seismic behavior, especially in controlling post‐decompression stiffness while also providing desirable ductile damage at very large seismic demands. The post‐decompression stiffness and load‐carrying capacity are mainly controlled by the stiffness of post‐tensioned (PT) elements and configuration of VFEDs.
