Abstract

In the framework of a research program sponsored by MIUR (Italian Ministry of University and Research), an experimental campaign was carried out on a real scale one storey one bay-by-two bays steel concrete composite space frame equipped with high damping rubber-based devices. The paper reports some results of the experiments. Firstly, free vibration tests were performed on the bare frame in order to determine its dynamic characteristics (stiffness, mass and damping ratio). Successively, after the same preliminary tests were performed on the frame endowed with the dissipaters, lateral displacement controlled excitations, in a frequency ranging from 0 to 3 Hz, as well as high frequency force controlled sine sweeps were performed aimed at fully investigating the behaviour of the braced composite structure.
