Nowadays,　some　innovative　spatial　structural　typologies　among　others　rely　on　timber-concrete　hybrid　solutions　for　designing　modern　buildings.　However,　the　dynamic　identification　analysis　may　be　more　elaborate,　and　sometimes　troublesome,　due　to　the　coupling　effects　of　the　different　dynamic　nature　of　cross-laminated　timber　and　reinforced　concrete　members.　In　the　current　manuscript,　the　authors　explore　some　preliminary　results　of　the　dynamic　analysis　of　a　hybrid　timber　concrete　building　case　study.　The　operational　modal　analysis　(OMA)　based　on　output-only　techniques　has　been　employed,　referring　specifically　to　enhanced　frequency-domain　decomposition　(EFDD)　and　the　stochastic　subspace　identification　(SSI)　methods.　The　authors　compared　several　ambient　vibration　OMA　results　with　forced　shaker-induced　vibration　responses　highlighting　the　absence　of　nonlinearities　during　in-service　operational　conditions　in　two　different　moments.　©　2024,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG.
