“…The increase of degrees of freedom can reduce the stiffness of soil-structure system, and then lengthen the natural period. Secondly, the foundation input motion is different from the free field motion due to the kinematic interaction and inertial interaction effects (Anand and Satish Kumar 2018). According to the response spectrum theory, the increase of the natural period and the change of the input motion can modify the seismic demand of the structure (Seed et al 1976).…”

“…Based on commonly used structure types in reality, it is essential to study the impacts of SSI on various kinds of structural systems to get a complete understanding of their seismic response. When subjected to seismic loading, the behaviour of any structure-soil system results from different factors, such as the input motion, type and depth of foundation, soil modulus and shear wave velocity, geometry and natural period of the superstructure (Anand and Satish Kumar 2018;Saleh et al 2018). In the past decades, many scholars have investigated the influence of SSI on moment resisting frames with low and mid-rise buildings (Tabatabaiefar et al 2013;Ghandil and Behnamfar 2017;Far 2019b;Yang et al 2020).…”

It is conventional to assume that the role of the soil-structure interaction (SSI) is beneficial to the buildings under seismic loading. However, lessons learned from recent earthquakes revealed that this assumption could be misleading, and SSI may have different effects on the seismic response of different structural systems. In this study, an enhanced soil-structure numerical model is developed and verified using ABAQUS software to assess the impact of SSI on high-rise frame-core tube structures. The seismic responses of 20, 30, and 40-storey buildings constructed on soil class Ee (according to Australian Standards) under four earthquake acceleration records have been studied. The results in terms of maximum lateral deflections, foundation rocking, inter-storey drifts and storey shear forces for the rigid base and flexible base frame-core tube structures have been discussed and compared.Generally, SSI has a remarkable impact on the seismic behaviour of high-rise frame-core tube structures since it can increase the lateral deflections and inter-storey drifts and decrease storey shear forces of structures. However, It is worth noting that the seismic responses of soil-structure systems under near and far field earthquakes are considerably different.

The present paper focuses on the optimum design of tuned mass damper (TMD) as a device for control of the structures. The optimum free vibration parameters such as period and damping ratio depend on the soil condition. For this reason, the seven meta-heuristic algorithms namely colliding bodies optimization (CBO), enhanced colliding bodies optimization (ECBO), water strider algorithm (WSA), dynamic water strider algorithm (DWSA), ray optimization (RO) algorithm, teaching-learning-based optimization (TLBO) algorithm and plasma generation optimization (PGO) are used to find the TMD parameters considering soil-structure interaction (SSI) effects. These optimization methods are applied to a benchmark 40-story structure. For comparison, the obtained results of these algorithms are compared. The capability and robustness of the algorithms are investigated through the benchmark problem. The results are shown that the soil type affects the optimum values of the TMD parameters, especially for the soft soil. To evaluate the performance of the obtained parameters in both the frequency and time domains, time history displacement and acceleration transfer function of the top story of the structure are calculated for the model with and without considering the SSI effects.

“…Hence, the vast majority of seismic vulnerability analyses consider models with a fixed-based configuration to obtain more conservative results. However, recent studies on the influence of SSI in the capacity assessment of buildings has proved that it does not positively affect all types of structures and all types of soils [2]. They have concluded that structures are expected to experience different levels of damage when the soil's influence is taken into account [3].…”

Most seismic vulnerability analyses do not consider the Soil-Structure Interaction (SSI). However, it has been proved that SSI does not equally affect all types of structures and all types of soils. The analysis of the state of the art reveals that SSI especially affects the performance of mid/high-rise buildings under soft/inelastic soil conditions. This leads to overestimating the capacity of buildings and to obtaining unreliable results. This paper aims to assess the soil influence in the seismic vulnerability analysis of a reinforced concrete (RC) building. Three models of a real case study building have been determined (low-rise (real), mid-rise and high-rise). A pre-code 1970s case study building, located in Huelva, has been selected. This building shares typical constructive and structural characteristics with most RC buildings constructed during that period. The 3D continuum model of the soil has been carried out to simulate its nonlinear behaviour. The most probable soil profile has been defined, observing a clayey soil. Therefore, the analyses have been performed under undrained conditions. Nonlinear static analyses have been carried out to determine the seismic capacity of the models through the finite element method (FEM). The damage has been assessed by means of the local procedure, defined in the European seismic code, and the global fragility procedure. The results have shown that the soil does not significantly influence the behaviour of low-rise buildings. However, in the case of mid-and high-rise buildings, the maximum capacity can be reduced by up to 10% and 30%, respectively.
