Abstract
The paper describes the distinctive features of the pseudo-dynamic test met hod as implemented at the ELSA reaction-wall facility. Both hardware and so ftware aspects are considered. Particular attention is devoted to the digit al control system and to a coupled numerical-experimental substructuring te chnique allowing realistic earthquake testing of very large structures. Mat hematical and implementation details corresponding to this testing techniqu e are given for both synchronous and asynchronous input motion. Selected te st results illustrate the advantages of the presented features. Copyright ( C) 2000 John Wiley & Sons, Ltd.
