Estudo da influência da taxa de amortecimento na modelagem reduzida via teoria da semelhança

Abstract

Two types of structures were fabricated in laboratory, and for these prototypes, reduced scale models were designed and constructed according to the structural elastic similitude conditions. These models were fabricated with different materials and geometric scales, and the number of joints in these two types of structures were modified. These variations in the models were imposed so as to verify their influence on the non-dimensional parameter: damping factors. It was observed that for the studied structures, the damping factors depend strongly on the material used in their fabrication. It is good to notice however, that all the tested structures have linear behaviour and no attempt was made to control the stress level in the joints.
