“…Moreover, the response of each structure in the group was compared to that of the singlestructure-soil system in order to find out whether or not SSSI effects can be of importance [14,15]. Therefore, we defined a variable J to measure the degree of the effects of SSSI, as shown in Equation (1).…”

“…The shortage of land resources has become a major issue to consider due to rapid urbanization. With urban development and population growth, the amount of buildings is more and more intensive [1]. Furthermore, the clear distance between adjacent buildings is generally smaller without the limit of annual probable sunlight hours in the east-west direction.…”

The dynamic structure-soil-structure interaction (SSSI) involving three adjacent structures with pile-raft foundations arranged along the east-west direction in a viscoelastic half-space is numerically studied under earthquake excitation. The direction of earthquake excitation is perpendicular to the direction of the structural arrangement. In the simulation, the Davidenkov model of the soil skeleton curve is assumed for soil behavior, and the viscous-spring artificial boundary is adopted. In order to investigate the effects of SSSI, the clear distance between structures, structure types, structure heights, and the first natural periods of structures are considered, and a series of numerical simulations are conducted. The peak floor displacement and the peak inter-story shear force of structures are examined to determine the SSSI effects. Results show that SSSI effects change significantly with these factors. Furthermore, the structural seismic response could be increased or reduced as a result of SSSI, depending mainly on the structural characteristics, rather than the location of the structures. These results are significant for studying the effects of SSSI and the sustainable development of cities, especially for the seismic design of dense urban buildings.

“…The results showed that SSI has significant influence on the pounding-involved structural response during earthquakes. Li et al (2017) studied the seismic pounding considering the structure-soil-structure interaction effect (SSSI) for a practical project considering pile foundation, box foundation and rigid foundation conditions. A three-dimensional finite element model was constructed utilizing ANSYS software.…”

The present research aims to study the influence of the soil-structure interaction (SSI) and existence or absence of masonry infill panels in steel frame structures on the earthquakeinduced pounding-involved response of adjacent buildings. The study was further extended to compare the pounding-involved behavior versus the independent behavior of structures without collisions, focusing much on dynamic behavior of single frames. The effect of SSI was analyzed by assuming linear springs and dashpots at the foundation level. The infill panels were modeled using equivalent diagonal compression struts. The steel frames were assumed to have elastic-plastic behavior with 1% linear strain hardening. The dynamic contact approach was utilized to simulate pounding between the adjacent buildings. Nonlinear finite element analysis was performed for two adjacent multi-story structures with four different configurations representing cases that can exist in reality. The seismic response of the studied cases generally emphasized that ignoring the soil flexibility and/or the contribution of the infill panels may significantly alter the response of adjacent structures. This may result in a false expectation of the seismic behavior of buildings exposed to structural pounding under earthquake excitation.

“…Case history on dynamic structure-soil-structure interaction analysis that considers adjacent tall buildings was also provided as a reference. A three-dimensional finite element numerical simulation using ANSYS was carried out by Li et al [16] as per Chinese design code for Shanghai soft soil with the rigid foundation, box foundation, and pile foundation. For simulation, the Davidenkov model of the soil skeleton curve was assumed for soil behavior, and the contact elements with Kelvin model were adopted to simulate pounding phenomena between adjacent structures.…”

In metropolitan cities, due to high land value structures are built very close to each other. During strong earthquakes, adjacent buildings with insufficient clear distances collide with each other causing architectural and structural damage or collapse of the whole structure. In addition to pounding, the interaction effects exchange the vibration energy between buildings making the problem further complicated. This paper attempts to provide a stateof-the-art review on the pounding of structures considering soil-structure interaction effects.
