Pseudo‐dynamic testing with substructuring at the ELSA Laboratory

The paper describes the distinctive features of the pseudo-dynamic test method as implemented at the ELSA reaction-wall facility. Both hardware and software aspects are considered. Particular attention is devoted to the digital control system and to a coupled numerical-experimental substructuring technique allowing realistic earthquake testing of very large structures. Mathematical and implementation details corresponding to this testing technique are given for both synchronous and asynchronous input motion. Selected test results illustrate the advantages of the presented features.
