Therefore, vibration serviceability is often one of the key criteria in the design of multi-storey timber buildings. In this article, we calculate the expected accelerations of wind-induced vibration for 10 timber and hybrid timber buildings with heights between 22 m and 74 m, for which we have obtained data on dimensions, mass and modal properties. The accelerations were calculated according to SIST EN 1991-1-4:2005 and evaluated according to ISO 10137. The parametric analysis showed that the location of the building has the greatest influence on the expected wind-induced accelerations. Among the parameters of the building shape, the radius of the rounded edges proved to have the greatest impact. It was also found that increasing the stiffness of the building contributes better to improving the comfort criterion for lower buildings, while adding mass is better for taller buildings. The analysis also included the current tallest timber building in the world and showed the potential for even taller timber buildings in the futureVečnadstropne lesene stavbe so zaradi svoje lahkosti občutljive na nihanje zaradi vetra, kar lahko povzroča neugodje pri uporabnikih. Zato je merilo ugodja stanovalcev pogosto eden ključnih kriterijev pri projektiranju večnadstropnih lesenih stavb. V članku izračunamo pričakovane pospeške nihanja zaradi vetra za deset lesenih in hibridnih lesenih stavb z višinami med 22 m in 74 m, za katere so bili pridobljeni podatki o dimenzijah, masi ter dinamičnih lastnostih. Pospeški so bili izračunani po SIST EN 1991- 1-4:2005 ter ovrednoteni po ISO 10137. Parametrična analiza je pokazala, da lokacija stavbe najbolj vpliva na njen odziv, izmed dejavnikov oblike stavbe ima največji vpliv zaobljenost oziroma prirezanost robov. Ugotovljeno je bilo tudi, da je za doseganje merila ugodja pri nižjih stavbah primerneje povečati togost, pri višjih pa dodati maso. V analizo je bila vključena tudi trenutno najvišja lesena stavba na svetu, analiza pa je pokazala potencial gradnje še višjih lesenih stavb v prihodnostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza društev gradbenih inženirjev in tehnikov Slovenije
