Abstract
The paper describes the distinctive features of the pseudo-dynamic test method as implemented at the largest European reaction-wall facility. Both hardware and software aspects are considered. Particular attention is devoted to the digital control system and to the time integration algorithms. A test-restart procedure well suited for stiff/brittle structures and a coupled numerical-experimental substructuring technique allowing realistic earthquake testing of very large structures are included. Finally a prospective view of continuous pseudo-dynamic testing is introduced. Selected test results illustrate the advantages of the presented features.
