Numerical evaluation of the modal characteristics of a bridge abutment
The seismic analysis of bridges needs to account for the effects of soil-structure interaction with methods that strike a reasonable balance between completeness and reliability of the numerical soil-structure interaction models. In view of this, focusing on the marked influence that the behaviour of the abutments can have on the seismic performance of the whole bridge, this study presents an identification procedure of the dynamic response bridge abutments.
