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 structural response of the controlled structure to the corresponding behaviour in the case of classical passive dampers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
