BEHAVIOUR OF TIMBER-TO-TIMBER CONNECTIONS WITH INTERPOSED RESILIENT SOUNDPROOFING PROFILE

This paper reports the mam outcomes of an ongoing research, supported by ROTHO BLAAS S.r.l. company, aimed at the experimental and theoretical characterization of timber-to-timber screwed connections with interposed an acoustic resilient profile for flanking noise reduction. The research is developed on two levels: experimental and analytical. An extended experimental campaign conducted on timber-to-timber screwed connections loaded in shear is presented. Obtained result are critically discussed in terms of observed failure mode, yielding condition and ductility. Experimental results are finally used to validate analytical models available in literature and specialized to account for the effect of acoustic interlayer on stiffness and load-carrying capacity.
