Pseudo-dynamic Testing of Large-Scale R/C Bridges in Elsa
Six large-scale (1:2.5) bridge specimens have been constructed and are being tested pseudodynamically at the ELSA laboratory. The tests are being conducted 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 is intended to provide background and improvement to the analysis and design methods. In particular, calibration and improvement of numerical models are sought. The first part of the programme (testing of four bridges) has been devoted to exploring different design solutions aimed at obtaining a more homogeneous ductility demand in irregular bridges. A test with isolation/dissipation devices to check the possibility to obtain a more homogenous ductility demand is being prepared. A test in which asynchronous base-motion will be simulated at the base of the piers is also foreseen. In this paper the series of pseudodynamic tests being conducted for the bridges with different reinforcement arrangements) as well as for a cyclic test of a squat pier are presented and discussed.
