Six large-scale (1:2.5) bridge specimens were constructed and tested pseudodynamically in the framework of the activities of the integrated European programme of pre-normative research in support of Eurocode 8 involving eighteen research institutions from the European Union. The experimental programme provides background and improvement to the analysis and design methods. In particular, calibration and improvement of numerical models were sought. The first part of the programme (testing of four bridges) was devoted to exploring different design solutions to obtain a more homogeneous ductility demand in irregular bridges. Tests to check the possibility of obtaining a more homogeneous ductility demand by means of seismic isolation were also carried out.
The series of pseudodynamic tests conducted for the bridges are described. The results obtained for part of the testing programme (regular and irregular bridges with different reinforcement arrangements and with seismic isolation) are presented and discussed.
