Within the context of this thesis study, comparative seismic performance assessment of skewed and curved integral and conventional bridges is examined. The thesis is mainly composed of two parts as the seismic performance of conventional and integral bridges under varying soil conditions. The two types of bridges mentioned are examined according to their skew and curvature levels. These bridges will have pile foundations at both abutments and piers. The local and global soil-pile interaction as well as the abutment-backfill interaction are modeled in order to examine the soil-structure interaction for both bridge types. Two, three and four span bridges are considered in this study. The analyses results indicate that the deck displacement increases as the degree of curvature increases. The effect of skew and curvature is deemed negligible on the axial forces underneath the piers. The shear forces underneath the piers and abutments deviate significantly depending on the angle of attack. As the soil softens, the reinforced concrete pile drift increases. The abutment height, thickness as well as the steel type used underneath the abutments generate the reactions based on the angle of attack.
