Soil-structure interaction (SSI) affects seismic demand and structural response but, excluding specific conditions, it is often neglected in design, assuming this leads to broader safety margins. The emerging scenario suggests that the evaluation of structural capacity, which is traditionally considered a purely structural property, seems to be influenced by SSI effects. This paper offers new insights into SSI, providing numerical evidence that the evaluation of structural capacity does not depend solely on structural properties but, it can be influenced by soil response and SSI. Implications on performance-based earthquake engineering (PBEE) are also discussed. The cast in-drilled-hole (CIDH) reinforced concrete pile-column of bridges has been selected as a case study.

Abstract
Soil-structure interaction (SSI) affects seismic demand and structural response but, excluding specific conditions, it is often neglected in design, assuming this leads to broader safety margins. The emerging scenario suggests that the evaluation of structural capacity, which is traditionally considered a purely structural property, seems to be influenced by SSI effects. This paper offers new insights into SSI, providing numerical evidence that the evaluation of structural capacity does not depend solely on structural properties but, it can be influenced by soil response and SSI. Implications on performance-based earthquake engineering (PBEE) are also discussed. The cast in-drilled-hole (CIDH) reinforced concrete pile-column of bridges has been selected as a case study.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
