“…Simultaneously, in the context of China's ongoing promotion of green low-carbon transformation and the advancement of building industrialization, it is imperative to develop a high-performance steel plate concrete composite structure system that integrates high-strength steel and high-strength, high-performance concrete. This will enable the achievement of a harmonious combination of enhanced load-bearing capacity, disaster resistance, lightweight characteristics, and ease of construction through the utilization of prefabricated assembly components [6][7][8][9][10], thereby facilitating its widespread application in large-scale industrial and civil buildings.…”

Against the backdrop of China’s continuous promotion of green and low-carbon transformation and the development of construction industrialization, high-strength composite structural systems have significant development prospects. However, their research and application in the field of construction are insufficient. In response to this issue, the study proposes a new high-performance structural system, namely the composite frame–high-strength steel plate wall core tube resilient structural system, which includes a core tube composed of double steel plate concrete composite shear walls and replaceable energy dissipation coupling beams, as well as composite frames. The highest strength grades of the steel plate and concrete used in the composite walls of the core tube are Q550 and C100, respectively. Using a 200 m building as an example, this study designs and establishes models for this high-performance structure and a conventional reinforced concrete frame–core tube structure. Subsequently, the dynamic elastoplastic time history analysis and seismic resilience assessment of structures are conducted under design basis earthquakes (DBEs), maximum considered earthquakes (MCEs), and extremely rare earthquakes (EREs). Research has shown that, compared to conventional structures, the thickness of shear walls of new high-performance structures can be effectively reduced, which helps decrease the self-weight of the structure and improve the available space in buildings. Additionally, high-performance structures exhibit a better performance in controlling the story drift ratio, lower plastic damage and overall stiffness degradation of the structure, and better seismic performance. The seismic resilience of the high-performance structure has been significantly enhanced, especially in terms of minimizing casualties, thereby better ensuring the safety of people’s lives and property.

“…In another study, Alavi [9,10] suggested that a channel-shaped stiffener with high torsional stiffness can be used as a more effective stiffener. Du [11] and Deng [12] used a multi-crenation network of channels and a diagonal channel to repair damaged SPSW. Channel stiffeners effectively repaired the damaged plate and reduced the tension field effect.…”

The use of steel shear wall in engineering construction, including high-rise building projects that bear high lateral forces, is of great importance and practical. Since the steel shear wall with opening may have some pre-cracks due to initial damage and cause the weak lateral behavior of the shear wall, in this study, the simultaneous impact of pre-crack and opening in the three-story and one-span frame with steel shear wall has been evaluated. In this study, 48 numerical samples have been studied using the finite element method and Abaqus software. Axial and lateral loading has been applied to the samples, and the parameters of the pre-crack position, pre-crack length and the type of shear wall steel sheet material have been investigated. The results of this study demonstrated that the numerical model made for the shear wall provides reliable answers compared to the laboratory model. In the shear walls under study, the parameter of crack length and crack position has a high impact on the ductility capacity, while it has little impact on the hardness and strength index. The most critical pre-crack modes in the horizontal position, located at the top or bottom corner of the frame, have had a great impact on the lateral behavior and reduced ductility by 60% and wall strength by 32%. On the other hand, by changing the materials of the shear wall steel sheet from LYP steel to St37 and St52, the final strength and hardness have increased by 3.63 and 1.45 times, respectively and the ductility has decreased by30%.

“…There are, however, some drawbacks to this approach, such as the fact that VBE's ability to mobilize web panel shear strength is lost and the panel's ductile behavior is diminished due to web plate out-of-plane displacement along the vertical free edges. The selfcentering brace was introduced to steel shear walls instead of the VBEs, by (Xu et al, 2021). This system was not utilized the poststrength of the steel panel; mainly, the energy dissipation and ductility of the structure were reported less than conventional SPSWs.…”

Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high ductility and efficient energy dissipation when subjected to seismic loads. This research investigates the seismic performance of an innovative infill web strip (IWS-SPSW) and a typical unstiffened steel plate shear wall (USPSW). As a result, two 1:3 scale specimens of an IWS-SPSW and USPSW with a single story and a single bay were built and subjected to a cyclic lateral loading methodology. In the prototype, semi-rigid end-plate connectors for the beam-to-column connections were utilized. The test result of IWS-SPSW showed outstanding ductility and shear load-bearing capacity without cracks or damage. Additionally, the IWS-SPSW exhibited strong energy dissipation without substantial beam-column connection distortion. USPSW showed excellent shear load-bearing capacity, low ductility, extensive infill plate corner tearing, and large infill web plate cracks. The FE models were developed and verified against experimental data. It has been shown that the infill web strips can affect the high performance and overall energy dissipation of an SPSW system. In addition, a parametric study was conducted to investigate the infill web strip material properties, such as steel strength and thickness, that can significantly enhance the system’s seismic performances.
