“…In addition, the investigation of these two phenomena simultaneously is attractive for the researchers to design the active multiple-tuned mass dampers for the asymmetric structure with SSI effect (Li, 2012). Recently, Birzhandi and Halabian (2018) presented a simplified method to consider the plan-asymmetry and SSI effects simultaneously in the nonlinear solution of seismically excited structures.…”

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.

This paper evaluates the accuracy of bidirectional energy-based pushover (BEP) procedure in predicting approximate incremental dynamic analysis (IDA) results for medium- and high-rise structures. BEP provides approximate IDA curves under the simultaneous effect of the two horizontal components of ground motions and is applicable to both symmetric- and asymmetric-plan buildings. The method has already proven useful in low-rise buildings, and this study aims to evaluate its suitability for mid- and high-rise structures. Six steel structures were considered in this evaluation in two groups of 9- and 20-story buildings, with each group consisting of a symmetric, a one-way asymmetric, and a two-way asymmetric-plan building. The assessment was performed for 22 pairs of far-field ground motion records. The results revealed that the accuracy of the method was satisfactory to produce approximate IDA curves for all structural models. The method had similar accuracy in the asymmetric models as it did in the symmetric models, although the accuracy showed a tendency to decrease as the height of the building increased. BEP also provided reasonable estimates of the demands in both 'flexible' and 'stiff sides' of the asymmetric buildings as well as the demands over the height of the buildings.
