  7. Abstract:
  8. In the last few decades Seismic Regulations attitude’s has been undergone significant changes from various aspects. One of these aspects is entering new topics based on the latest scientific achievements. Soil-Structure Interaction terms was from such issues which had found their ways into Seismic codes as an optional effective factor. In recent years, Based on this new attitude and Scientific achievements, Soil-Structure Interaction terms entrance into Iranian seismic code (2800 Standard), is also has been studied. Naturally, applying these criteria will impact on the design and performance of structures, because of reducing effect of soil structure interaction on decreasing base shear design force. The rate of decrease depending on the structural system and the soil type is permitted up to 30 percent. This reduction in design base shear can significantly impact the design of buildings and their performances at moderate and strong earthquakes. In this thesis, Reduction in base shear for different structures has been examined and the impact of this reduction has been evaluated in Designing and performance of these structures by considering the effect of soil-structure interaction. According to conducted study, Base shear decline caused by soil-structure interaction has a significant impact on the performance of structures and increases ductility demand sharply. The study also evaluated the performance assessment of structures based on ASCE41 criteria, to determine the effect of soil-structure interaction and the resulting reduced base shear on the performance of different structures
