20.500.12556/DiRROS-22822 Parametrična analiza odziva večnadstropnih lesenih stavb na vetrno obtežbo Parametric analysis of the response of multi-storey timber buildings to the wind loading Večnadstropne 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 prihodnosti. Due to their light-weight nature, multi-storey timber buildings are susceptible to wind-induced vibration, which can cause discomfort to the occupants. 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 future. lesene stavbe vetrna obtežba nihanje stavbe mejno stanje uporabnosti parametrična analiza timber buildings wind loading building oscillations serviceability limit state parametric analysis true false false Slovenski jezik Angleški jezik Neznano 2025-07-01 09:15:52 2025-07-01 09:18:24 2025-10-24 03:52:16 0000-00-00 00:00:00 2025 0 0 Nasl. v slov. in angl., besedilo v slov.; str. 68-77 Št. 2 Letn. 74 jun. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-06-01 69.032.2+624.011.1:531.1 0017-2774 240283907 https://www.zveza-dgits.si/wp-content/uploads/2025/06/GV-06-25-1.pdf 0 a3c4fa58-564b-11f0-8080-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=33179 GV-06-25-1.pdf GV-06-25-1.pdf 1 71035FBA289D5C028EB4A5398F3E99E4 ad311bb76dc460327fe65bd951ccc914f1fa7fd015e131f664dd169226638054 3972f055-564b-11f0-8080-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=33175 Zveza društev gradbenih inženirjev in tehnikov Slovenije Gradbeni vestnik 0 0 0
