The present article aims to provide an overview of the consequences of dynamic soil-structure interaction (SSI) on building structures and the available modelling techniques to resolve SSI problems. The role of SSI has been traditionally considered beneficial to the response of structures. However, contemporary studies and evidence from past earthquakes showed detrimental effects of SSI in certain conditions. An overview of the related investigations and findings is presented and discussed in this article. Additionally, the main approaches to evaluate seismic soil-structure interaction problems with the commonly used modelling techniques and computational methods are highlighted. The strength, limitations, and application cases of each model are also discussed and compared. Moreover, the role of SSI in various design codes and global guidelines is summarized. Finally, the advancements and recent findings on the SSI effects on the seismic response of buildings with different structural systems and foundation types are presented. In addition, with the aim of helping new researchers to improve previous findings, the research gaps and future research tendencies in the SSI field are pointed out.

“…In 1960, Veletsos and Newmark (1960) studied and defined the inelastic displacement ratio spectra for the first time. Since then, scholars have performed plenty of statistical analysis on the inelastic displacement ratio spectra of different nonlinear structures through time-history analysis, and proposed different prediction formulas (e.g., Miranda 2001;Wen et al 2014;Hassani et al 2018;Bararnia et al 2018;Yaghmaei-Sabegh et al 2017;Konstandakopoulou et al 2020;Wu et al 2019). Currently, research on the inelastic ratio spectra mainly focuses on common elastic-plastic structures, and the constitutive models of these structures mainly include the bilinear model, elastic-plastic model, and degradation model.…”

Previous researches on the constant ductility inelastic displacement ratio spectra (𝐶 μ ) of self-centering structures have been conducted based on the typical flag-shaped self-centering (FS) model. However, the arising shape-memory-alloy-friction self-centering structures (SMAFSs) own their specialized force-displacement relationship different from the typical FS model. In this research, a hybrid force-displacement model composed of the typical FS model and Coulomb friction model is employed and an efficient calculating procedure is proposed to statistically investigate the 𝐶 μ of SMAFSs. Comparison with the 𝐶 μ of the typical FS system with similar selfcentering capacity shows that the 𝐶 μ of the SMAFS is significantly different from that of the typical FS system, which explains the necessity of employing the hybrid model for SMAFSs and the effects of the friction. The effects of seismic parameters and structural parameters on the 𝐶 μ of SMAFSs are investigated. Furthermore, the formula for estimating the 𝐶 μ of SMAFSs is proposed through statistical regression. This proposed formula could estimate the 𝐶 μ of SMAFSs and describe the effects of structural parameters more accurately. The research could provide a basis of estimating the 𝐶 μ of SMAFSs to obtain reliable seismic design results of the structures.

“…Seismic response of reinforced concrete tall structures to the near-fault earthquakes considering the SSI has been investigated by Galal and Naimi (2008). Recently, the inelastic displacement ratios for soil–structure systems with embedded foundation have been investigated by Bararnia et al (2018). They found that using the inelastic displacement ratios of fixed base structure evaluates an underestimated demands for soil–structure systems.…”

This study aims to evaluate the torsional effects and soil-structure interaction simultaneously under near-fault pulse-like earthquakes in a probabilistic framework. Incremental dynamic analysis and fragility curves are employed for this goal. An eight-story R/C dual lateral load-resistant building consisting of shear walls and moment resisting frames is used. The median incremental dynamic analysis curves reported the maximum capacity for the symmetric structure in each foundation conditions. In addition, the capacity of structure will be increased when more shear wave velocity is assumed. Therefore, from this view, neglecting the soil-structure interaction will not be in the safe side. Fragility curves (using intensity measure directly) show that for different cases (except for very low shear wave velocity), more value of eccentricity leads to more probability of collapse. Moreover, the fragility curves show that (for each eccentricity), soil-structure interaction effect is significant only for the flexible base structure with the very low shear wave velocity (100 m/s) and more eccentricity value leads to less soil-structure interaction effects. Results show that the significant eccentricity value may lead to reduce the soil-structure interaction effect in the shear-wall structures under the near-fault events.
