“…Also, the modulus of elasticity, the yield stress, the tensile strength, and the Poisson's ratio for the steel materials were considered 200 GPa, 280 MPa, 410 MPa, and 0.3, respectively. The validation of the methodology for the nonlinear behavior of buildings can be found in 1,74 . The inelastic performance of the beam components can be properly simulated with the plastic hinges at their two ends, as recommended by some previous studies, 73,75,76 while the schematic moment‐rotation ( M‐θ ) behavior of the inelastic hinges in this study is shown in Figure 5.…”

“…The previous papers on TSSI analysis 1,15 show that slope topography for a building alone does not significantly affect the global performance of 5-story low-rise buildings. On the other hand, Bybordiani and Arici 85 concluded that for clusters of 5-story similar buildings, the drift and base shear responses could be low as 5% compared to the SSI solution.…”

“…The recorded data during previous earthquakes indicate that slope topographic effects can play an essential role in making various characteristics of strong ground movements. [1][2][3] The impact of this kind of topography is evident in the most destructive earthquakes of history, namely, Canal Beagle Chile 1985, Whittier Narrows 1987, Aegion Greece 1995, and F I G U R E 1 Building groups near the slopes and damage to the buildings in the SarPol-e Zahab earthquake Athens Greece 1999. 4,5 Drawing on field observations as well as experiences of previous earthquakes, researchers found that either deep or surface heterogeneity of topography has essential effects on seismic response and the extent of damages.…”

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.
