This paper reports the results of research on the application of dissipating braces for the earthquake protection of steel-concrete composite structures. Attention is focused on HDRbased dissipation devices. The first part of the paper reports the results of an experimental campaign on HDR dissipation devices and an analytical model based on a rheological thermodynamically compatible approach is outlined. In the second part, the design criteria of a mock-up of a steel-concrete composite space frame are discussed. The results of the dynamic characterization of the bare frame are also reported. Finally the results of some preliminary free vibration tests performed on the frame equipped with the HDR devices are shown in order to understand the dynamic response to imposed initial displacements.

Abstract
This paper reports the results of research on the application of dissipating braces for the earthquake protection of steel-concrete composite structures. Attention is focused on HDRbased dissipation devices. The first part of the paper reports the results of an experimental campaign on HDR dissipation devices and an analytical model based on a rheological thermodynamically compatible approach is outlined. In the second part, the design criteria of a mock-up of a steel-concrete composite space frame are discussed. The results of the dynamic characterization of the bare frame are also reported. Finally the results of some preliminary free vibration tests performed on the frame equipped with the HDR devices are shown in order to understand the dynamic response to imposed initial displacements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
