The DYSCO Virtual Laboratory is the first example in Italy of remotely shared experimental tests on a network platform consisting of two large scale 6DOF oleo dynamic seismic tables and two electro dynamic shakers at the MAT-QUAL laboratories of the ENEA Casaccia research Center in Rome, for seismic, mechanical, aerospace and nuclear applications.
The connection to DYSCO virtual laboratory is provided by the ENEAGRID of numerical computation, and more specifically by ENEA-CRESCO facilities ( Computational RESearch center on COmplex system ): the results are shared in real time via Internet among the partners of the experiment and stored in ENEA web pages for future use and for every remote user who can visualize them by different access privileges.
As the experimentation goes on, remote users have the possibility to interact step by step with the experts of the DYSCO laboratory, exchanging opinions about the results and, if necessary, agree the modifications in the subsequent steps of the experiment.
One of the goals of this project is also to implement the process of vibration and seismic qualification for nuclear components and system: the remote control allows the customer to immediately analyze the results together with the ENEA scientists and visualize where the problem for a non-qualification notify is. The DYSCO Virtual laboratory comes from many research projects of seismic protection for civil structures like as: TREMA, RELUIS and TELLUS STABILITA.

Beside the traditional sensors (accelerometers, LVDT) normally used in qualification tests, within DYSCO the data acquisition are performed by a new, innovative, high resolution 3-D optical movement detection and analysis tool. Its purpose is to track the dynamic displacement of several selected points of the structures during the dynamic tests of natural (earthquake) and artificial (mechanical) induced vibrations by the shaking-table. This system uses twelve high resolution Infrared Cameras to measure accurate 3-D positions of hundred of markers placed on the structure during the seismic tests.
The possibility to synchronize visible and infrared cameras allows the remote participation and control of the shaking table tests in a networking configuration of distributed experiments.
The innovative monitoring technique measures 3 axial absolute displacements with easy and fast test set-up, high accuracy and the possibility to link the 3D-motion time histories of the tracked markers with CAD drawings of the structure and validate the FE models in real time experimental data assimilation. The measure of the displacements is a crucial task for the numerical and experimental studies in structural dynamics, especially within the displacement based approach in seismic design and calculations.

The ENEA grid and the CRESCO system with its capabilities of parallel computational, give to the remote user the opportunity to run the heavy finite element structural analysis codes by the most important commercial software available by CRESCO.
