Abstract

Structural active control systems have not yet completely passed the theoretical stage and only in few cases all over the world it has been possible to obtain a full experimental validation. At the moment, there is a lack of experimental evidence confirming the theoretical concepts shown in a quite large scientific literature. The present paper describes the experimental activity related to an effort to experimentally validate a control system based on a simple control algorithm and on a prototype semi-active magnetorheological damper. Starting from the definition of the proper control law and the analysis of the behaviour of the prototype semi-active device, the experimental activity comprised many shaking table tests on a 4-story steel frame which allowed to compare the
