Connessioni trave-colonna dissipative per attrito sono sempre pi˘ frequentemente impiegate per la realizzazione di strutture antisismiche resilienti grazie alla loro facilit‡ di progettazione, affidabilit‡ di comportamento, ridotta perdita di prestazioni nel tempo e influenza del comportamento dalle condizioni ambientali, nonchÈ elevate prestazioni garantite da grande rigidezza, facilit‡ di regolazione della resistenza della connessione, elevata e stabile capacit‡ dissipativa e ridotta complessit‡ costruttiva. Qui vengono riportati i risultati dei test condotti su dispositivi di attrito lineare, che Ë il componente principale della connessione dissipativa, e su un prototipo in scala reale di una connessione fra trave reticolare in acciaio ibrida in calcestruzzo (HSTCB)-colonna recentemente proposta. Per analizzare in modo approfondito la funzionalit‡ del dispositivo di attrito proposto in termini di dissipazione di energia, Ë stato testato sotto cinque carichi ciclici con diverse ampiezze. I risultati hanno dimostrato l'efficacia delle soluzioni tecniche adottate per la progettazione del dispositivo

Abstract
Friction dissipative beam-to-column connections are rising popularity to design resilient earthquake-resistant structure due to their ease of design, reliability of behavior, reduced loss of performance over time and influence of environmental conditions on the behavior. High performance is guaranteed by high initial stiffness, ease of tunning connection strength, high and stable dissipative capacity, and reduced construction complexity are further appreciated features. The research is focused on test results conducted on linear friction devices, which is the main component of the dissipative connection, and on a full-scale prototype of a recently proposed friction-based hybrid steel trussed concrete beams (HSTCBs)-to-column connection for moment resisting frame. In order to deeply analyze the functionality of proposed friction device in term of energy dissipation, it has been tested under five cyclic loadings with different amplitudes. The results proved the efficiency of the technical solutions adopted for the device design.File | Dimensione | Formato | |
