Assessment of the Effects of Soil-Structure Interaction on the Seismic Response of the RC Frame Buildings by Developing Seismic Fragility Curves Based on SPO2IDA Analysis
Ground vibrations caused by soil-structure (SSI) can be magnified or de-amplified, and estimating them is essential for seismic designs and fragility assessments.Field survey reports show that SSI is an important factor causing severe damage to structural elements, especially in soft soils that have been exposed to an earthquake.The soil-structure
