EnglishThe paper analyzes the influence of double concave friction pendulum (DCFP) isolator properties on the seismic performance of isolated bridges. The behavior of these systems is analyzed by employing an eight-degree-of-freedom model accounting for the first five vibra-tional modes of the pier and the presence of a rigid abutment, whereas the DCFP isolator behaviour is described combining two single FPSs in series. The uncertainty in the seismic input is taken into account by considering a set of natural records with different character-istics. The variation of the statistics of the response parameters relevant to the seismic per-formance is investigated through an extensive parametric study carried out for different sys-tem properties.

| Abstract: | The paper analyzes the influence of double concave friction pendulum (DCFP) isolator properties o...n the seismic performance of isolated bridges. The behavior of these systems is analyzed by employing an eight-degree-of-freedom model accounting for the first five vibra-tional modes of the pier and the presence of a rigid abutment, whereas the DCFP isolator behaviour is described combining two single FPSs in series. The uncertainty in the seismic input is taken into account by considering a set of natural records with different character-istics. The variation of the statistics of the response parameters relevant to the seismic per-formance is investigated through an extensive parametric study carried out for different sys-tem properties. | |
