“…Recent advancements in SSSI analysis have seen significant progress, with researchers developing new methods and models to understand the behavior of multiple structures interacting with soil [10][11][12][13][14]. Using Finite Element Analysis (FEA) is one such method, considering factors like soil stiffness, foundation shape, and loading conditions [11].…”

“…These studies have highlighted the need for accurate modeling and analysis of SSSI to ensure the safety and reliability of these structures. For example, researchers have used FEA to analyze the effects of SSSI and SSI on tall buildings during earthquakes and fount that adjacent buildings can significantly affect each other's behavior due to soil movement and deformation [10]. Bariker and Kolathayar [18] have employed the FEA method to analyze a new foundation construction.…”

This paper introduces an innovative approach to numerically model Structure–Soil-Structure Interaction (SSSI) by integrating the Boundary Element Method (BEM) and the Finite Element Method (FEM) in a coupled manner. To assess the accuracy of the proposed method, a comparative study is undertaken, comparing its outcomes with those generated by the conventional FEM technique. Alongside accuracy, the computational efficiency aspect is crucial for the analysis of large-scale SSSI problems. Hence, the computational performance of the coupled BEM–FEM method undergoes a thorough examination and is compared with that of the standalone FEM method. The results from these comparisons illustrate the superior capabilities of the proposed method in comparison to the FEM method. The novel approach provides more reliable results compared to traditional FEM methods, serving as a valuable tool for engineers and researchers involved in structural analysis and design.

“…To date, frame structures and bridge engineering are focal points in SSI research. In both numerical and experimental investigations of SSI, more than half of the addressed superstructures involve multi-layer frame structures and adjacent steel or concrete structures [7]. Sections 3 and 4 will go into more detail on these structures.…”

Soil–structure interaction (SSI), which characterizes the dynamic interaction between a structure and its surrounding soil, is of great significance to the seismic assessment of structures. Past research endeavors have undertaken analytical, numerical, and experimental studies to gain a thorough understanding of the influences of SSI on the seismic responses of a wide array of structures, including but not limited to nuclear power plants, frame structures, bridges, and spatial structures. Thereinto, large-span spatial structures generally have much more complex configurations, and the influences of SSI may be more pronounced. To this end, this paper aims to provide a state-of-the-art review of the SSI in the seismic assessment of large-span spatial structures. It begins with the modelling of soil medium, followed by the research progress of SSI in terms of numerical simulations and experiments. Subsequently, the focus shifts towards high-lighting advancements in understanding the seismic responses of large-span spatial structures considering SSI. Finally, some discussions are made on the unresolved problems and the possible topics for future studies.

“…The vibrational energy from the structure can influence nearby structures through the soil medium [6,7]. The vibration characteristics and seismic response of a building cannot be considered independent of those of adjacent buildings [8]. An earthquake is a natural phenomenon, which is generated in the earth's crust.…”

This study examines the seismic performance of nuclear containment structures on a layered fine sand to Hard rock. The research explores the intricate dynamics of nonlinear soil behaviour during earthquakes and its significant impact on soil-structure interactions. This analysis considers the inherent nonlinearity of the containment structure and the soil under various conditions, utilizing models such as the heterogeneous elastic soil model and heterogeneous mech mohr model. These models incorporate varying properties and are implemented using the FLAC3D software. Notably, the proportions of the heterogeneous soil model, silty clayey soil model, and dense sand soil model are 83.17%, 85.42%, and 25.93%, respectively. An interesting observation is that the silty clayey model exhibits a higher poisson’s ratio (0.42) than the Hard Rock Model (0.24), resulting in a lower vertical stress azz in the Silty Clayey Model. The study found that some soil models are more effective under certain loading conditions. This provides new insights into how to best apply these models for accurate soil-structure interaction (SSI) modelling. This enhanced understanding of the capabilities of different soil models under various conditions is valuable for future research and has significant implications for practical applications in geotechnical earthquake engineering, especially for the safety of nuclear structure in seismic-prone regions.
