The paper presents the state of art of a research activity focusing on an innovative connector system, the collar connector, appropriately conceived for new composite timber-concrete floors and for stiffening and strengthening existing ones. Preliminary numerical analyses and experimental tests were developed on both rectangular and circular specimens, made of new and ancient timber respectively. In particular, monotonic push-out tests on different types of collars, which correspond to further improvements and optimization of the system, and bending tests on either timber-concrete beams or full-scale floor equipped with collar connectors, were performed. Then, the collar connector system was applied to a historical timber floor belonging to the Royal Palace of Naples (Italy).

Abstract
The paper presents the state of art of a research activity focusing on an innovative connector system, the collar connector, appropriately conceived for new composite timber-concrete floors and for stiffening and strengthening existing ones. Preliminary numerical analyses and experimental tests were developed on both rectangular and circular specimens, made of new and ancient timber respectively. In particular, monotonic push-out tests on different types of collars, which correspond to further improvements and optimization of the system, and bending tests on either timber-concrete beams or full-scale floor equipped with collar connectors, were performed. Then, the collar connector system was applied to a historical timber floor belonging to the Royal Palace of Naples (Italy).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
