“…With notable exception that of the 1985 Mexico earthquake [2], the effect of SSI to steel structures subjected to far-fault seismic motions seems to be marginal. So far, only a few parametric studies have been carried out on the investigation of the effect of SSI to steel structures [3][4][5][6][7][8][9][10].…”

The seismic performance of steel structure-foundation systems subjected to near-fault earthquakes was assessed on the basis of response results from nonlinear time-history seismic analyses. The structural results included the maximum values for residual interstory drift ratios, base shears, and overturning moments of the steel structures, as well as the maximum values for residual settlement and tilting of the foundations. In order to reveal the influence of soil-building-interaction on the aforementioned response results, the steel building-foundation systems were designed according to Eurocode 8 provisions, assuming initially fixed and then compliant base conditions. It was concluded that for the case of near-fault seismic motions, good seismic performance of steel building-foundation hybrid systems designed according to European Codes was not guaranteed. A particular thing to note for these systems under near-fault seismic motions was that the seismic performance of the steel structure was most likely unacceptable, while one of the foundations was always acceptable.

“…In addition, they showed that SSI increases the drift demand. Behnamfar and Banizadeh showed that, with a flexible base, the location of maximum drift moves to the first story where the most severe vulnerability is observed [32]. They showed that SSI changes the pattern of distribution of vulnerability, especially for the beams of shear wall buildings, and increases the seismic vulnerability on soft soils.…”

“…One of the issues that can affect the seismic response of structures is soil-structure interaction (SSI), which has been investigated by many researches (e.g., [30][31][32]). Depending on the stiffness of the soil, the seismic performance and energy dissipation of structures can significantly be changed by considering the SSI effects.…”

This paper presents the probabilistic generation of collapse fragility curves for evaluating the performance of 3D, reinforced concrete (RC) moment-resisting building models, considering soil-structure interaction (SSI) by concentration on seismic uncertainties. It considers collapse as the loss of lateral load-resisting capacity of the building structures due to severe ground shaking and consequent large interstory drifts intensified by -Δ effects as well as the strength and stiffness deterioration of their lateral load carrying systems. The estimation of the collapse performance of structures requires the relation between the intensity measure (IM) and the probability of collapse that is determined using the generated collapse fragility curves. Considering a number of 6-, 12-, and 18-story, 3D, RC moment-resisting buildings, two scalar IMs are employed to estimate their collapse fragility curve. On the other hand, the effect of the site soil type on the collapse fragility curves was taken into account by considering the soil-structure interaction. According to the obtained results, adopting the average of spectral acceleration (Saavg) intensity measure is more efficient in capturing the effect of the inherent uncertainties of the strong ground motions on the structural response parameters. In addition, considering the SSI for soil type D with shear-wave velocity of 180 m/s to 360 m/s reduces the median of intensity measure (IM = Sa( 1 )) of fragility curve in 6-, 12-, and 18-story buildings by 4.92%, 22.26%, and 23.03%, respectively.

“…Several investigations on the inelastic seismic response of structures with setbacks indicate that, compared to regular frames, there was a noticeable change in the seismic response of frames with setbacks (Shakib and Pirizadeh 2014). Furthermore, the seismic response of structures with setbacks that are located on the soft soil was more complex and should be considered when designing this type of structure (Shakib and Homaei 2017). Nievas and Sullivan (2015) successfully proposed the use of a direct displacement-based design method for MRFs with setbacks.…”

Vibration control of structures has been a focus of research worldwide. Although, several studies have examined the efficiency of semi-active tuned mass dampers (SATMDs) to control the seismic vibration of structures, only a few have focused on the influence of SATMDs on steel moment resisting frames in irregular structures having setbacks. In the current investigation, the use of SATMDs for the vibration control of structures with setbacks subjected to earthquake records has been evaluated. In order to assess the nonlinear seismic performance of buildings with setbacks, the inter-story drift ratio, story displacement, and base shear factor were examined as engineering demand parameters. The results reveal that the use of SATMDs reduced the seismic response of regular and irregular frames with setbacks. However, the use of these control devices requires more attention for structures with significant setbacks because, in some cases, the response of a structure with SATMDs can be greater than of an uncontrolled structure. The investigations also showed that placement of the control systems at the highest (top) level of the structure significantly reduced the structural vibration of both types of structure.
