20.500.12556/RUL-154868 Modelling of multi-storey cross-laminated timber buildings for vibration serviceability In this study, the vibration serviceability of multi-storey timber buildings is addressed. The core of this study pertains to the preparation of a comprehensive finite element model to predict modal properties for an accurate vibration serviceability checking. To that end, findings obtained from studying three multi-storey timber buildings are summarized and discussed. Two of the buildings (of seven and eight storeys) consist entirely of cross-laminated timber (CLT), while the third is a five-storey hybrid CLT-concrete building. Thanks to the detailed finite element models and modal testing results, one has the capability to conduct sensitivity analyses, classical and Bayesian model updating, and uncertainty quantifications. With these methodologies, influential modelling parameters as well as the sources of modelling error were identified. This allowed for conclusions to be drawn about the in-plane shear stiffness of the constructed walls (whose higher v alue causes the natural frequencies to increase by up to 25%), the soil deformability (which may cause the natural frequencies to drop by up to 20%), and the perpendicular-to-the-grain deformation of floor slabs (which may lead to an overestimation of a fundamental frequency by up to 8%). civil engineering timber buildings cross-laminated timber modal testing modal properties finite element modelling model updating vibration serviceability gradbeništvo lesena stavba križnolepljene plošče modalno testiranje modalne lastnosti modeliranje s končnimi elementi posodabljanje modela vibracijska uporabnost true false true Angleški jezik Slovenski jezik Članek v reviji 2024-03-06 16:00:46 2024-03-06 16:00:55 2024-03-07 03:57:30 0000-00-00 00:00:00 2024 0 0 Str. 1-21 letn. 14 Št. 3, art. 689 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 699.8 2075-5309 10.3390/buildings14030689 187931139 buildings-14-00689_(3)_(1).pdf buildings-14-00689_(3)_(1).pdf 1 6DDD5308BB2301C886EC58E7272B2AB8 1e8d3ca653a279e222aeee3ca19a864c1f95255acde7ac71540babd1f96a93ff fe69876d-dbca-11ee-bf12-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181496 https://www.mdpi.com/2075-5309/14/3/689 1 55483fac-dbca-11ee-bf12-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181494 Fakulteta za gradbeništvo in geodezijo 0 0 0
