Abstract

This paper discusses the implementation of the pseudo-dynamic (PSD) method based on a distributed digital control of the electrohydraulic loop developed in the JRC's new Reaction Wall Facility, ELSA. After an introduction to the PSD method, a short description of the distributed digital control is given and the main advantages of such a configuration are presented. Special attention is devoted to the structural displacement accuracy obtained by using a digital transducer. The basic mathematical formulation of the explicit and implicit integration algorithms which have been used in the development of the PSD tests are also described. The results of validation tests performed on multiple degree of freedom (MDoF) structures and employing explicit and implicit integration schemes, correlates well with real-time dynamic tests.
