“…The prolonged natural period results in further decrease of spectral acceleration. Bagheri et al (2018) carried out numerical simulations on 15-storey and 30-storey frame structures rested on six types of pile foundations to study the seismic behaviour of the structures. The numerical results indicated that the performance level of the structures is related to the pile configuration, ground motion features and height-width ratios of the superstructures.…”

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.

“…Von Mises constitutive model with isotropic hardening was selected for steel, and the damaged plasticity model was chosen for concrete. The concrete damage plasticity model is one of the most widely used constitutive models for concrete simulation in ABAQUS software, which has been used in various articles [7]. This model simulates the mechanism of failure in tension and compression in a continuum space using the damage parameter, which is a function of non-elastic strain.…”

“…The presence of soil increases the acceleration of the earthquake transmitted to the structure and increases the flexibility of the structure [6]. The first factor is the cause of more seismic damage in structures *Corresponding Author Institutional Email: zarinfar@basu.ac.ir (M. zarinfar) built on soft soil than in structures built on hard soil, so that the performance of the structure may change from the life-safe to a near-collapse without considering the interaction of the structure and the soil [7,8]. The second factor reduces the frequency of the soil-structure system.…”

Considering soil layering is a crucial and effective issue in investigating the seismicity of structures. However, previous studies have not examined the presence of a rock layer in soft soil. So, in the present paper, the effect of the rock layer in soft soil on the forces and displacements created in the low-and midrise steel moment frame was investigated. Thus, several numerical calculations were performed on 12 different sizes of rock layers at three different depths. Finite element models were analyzed using ABAQUS Software and considering the interaction of structure and soil. Results of the studies showed that the value of force and displacement depends on the frequency of the structure, the frequency of the soil-structure system, dominant earthquake frequency, the rock weight, and the stiffness of the structure. Two new parameters are defined that have a linear relationship with force and displacement. Results show that the thickness and length of the rock layer affect the value of force and displacement. Also, the presence of a rock layer in the soil may not be reliable and may increase the shear force by up to 27%, the axial force by up to 10%, and the moment by up to 19%. The effect of the presence of a rock layer on the displacement is more than on the force and increases the lateral displacement by up to 31% and the relative vertical displacement of the foundation by up to 59%.

“…Although Caughey damping, which enables far more modes to be damped with a ratio ξ, is expected to be more suitable for modeling, MIDAS software does not cover this type of damping. It should be noted that many previous studies on continuum models of SSI 57,[69][70][71] and TSSI 5,39,45,48 with a very large number of DOFs have used Rayleigh damping to simulate soil and structures. In other words, the efficiency of this type of damping in nonlinear dynamic analyzes has been well established in previous studies.…”

The occurrence of vibrational energy exchange between neighboring buildings via soil is a well-known issue today as structure-soil-structure interaction (SSSI) problems. Furthermore, the seismic performance of buildings near the slopes considering seismic topography-soil-structure interaction (TSSI) is entirely different from their performance on the flat grounds considering seismic soilstructure interaction (SSI). Therefore, this study evaluates the seismic response of three moments resistant frame steel buildings with 15, 10, and 5 stories using three dimensional numerical analysis as a new topography-structure-soilstructure interaction (TSSSI) problem. This issue has not been investigated in previous studies to the best of the authors' knowledge. In each case of TSSSI, two, three, and four buildings with similar dynamic properties were simulated simultaneously. The effects of foundation's rocking, numbers of buildings, and the 2D and 3D arrangements of buildings were investigated, and the results of TSSSI cases were compared with the corresponding SSSI cases. The inelastic behavior for both building components and soil was considered in the simulations. Analyzes are performed based on seven earthquake records from which the average value was taken as final results. Results show that it is essential to consider the TSSSI effect, and it can completely change the seismic performance of buildings near the slopes. Although the effects of TSSI and SSSI on the seismic responses of the low-rise similar structures are negligible relative to the SSI cases, the results show that the nonlinear TSSSI effects of adjacent buildings should be fully considered even for 5-story low-rise structures.
