Abstract text:
The present work describes part of the Research & Development (R&D) on using a semi-active structural control technique in a civil engineering experimental model frame equipped with a magneto-rheological (MR) damper, developed within COVICOCEPAD project approved in the framework of Eurocores program S3T. Some results are provided associated with the calibration of a MR damper at FEUP (Faculdade de Engenharia da Universidade do Porto) as well as on the experimental modal identification of the dynamic properties of a small-scale metallic frame, with and without the inclusion of a specific MR device. Some numerical results of the controlled frame under simulated earthquakes are given, to be later compared with the experimental results of such frame installed in a Quanser shaking table.
Key Words:
response control; MR dampers; semi-active control.
