ABSTRACT. THIS PAPER INVESTIGATES THE INFLUENCE OF SCALE AND MATERIAL ON THE DAMPING FACTOR OF STRUCTURES. IN ORDER TO EVALUATE THAT, TWO DIFFERENT TYPES OF STRUCTURES WERE FABRICATED IN LABORATORY. FOR THESE PROTOTYPES, REDUCED SCALE MODELS WERE DESIGNED AND CONSTRUCTED ACCORDING TO THE STRUCTURAL ELASTIC SIMILITUDE CONDITIONS, USING DIFFERENT SCALES AND MATERIALS. ALSO, THE NUMBER OF JOINTS WERE VARIED FOR THE TWO PROTOTYPES. IT CAN BE OBSERVED FROM THE RESULTS PRESENTED IN THIS PAPER THAT THE DAMPING FACTOR DEPENDS STRONGLY ON THE MATERIAL USED WHEREAS THERE IS NO INFLUENCE DUE TO THE SCALE ADOPTED. HOWEVER, IT SHOULD BE NOTICED THAT ALL TESTED STRUCTURES HAVE LINEAR BEHAVIOUR AND NO ATTEMPT WAS MADE TO CONTROL THE JOINTS STRESS LEVEL.
KEY-WORDS: SIMILITUDE CONDITIONS, DAMPING FACTOR, EXPERIMENTAL ANALYSIS, STRUCTURES
