خلاصه مقاله:
Due to the destructive effects of near-fault earthquakes and soil effects, the aim of this study is to investigate the effect of these parameters on isolated bridges. Real earthquake records with different distances of fault are chosen and investigated. Results in terms of deck acceleration, base shear, displacement and the performance of isolator are studied and compared by nonlinear time history analysis in SAP2000. Results demonstrate that for NF zones, considering the soil effect, is imperative. In soft soils, seismic responses are amplified. Designing isolator without taking this fact into account will cause inappropriate design with lower capacity

کلمات کلیدی:
