20.500.12556/DKUM-99569 Uporaba LVL lesnih kompozitov v leseno-montažni gradnji Use of LVL wood composites in prefabricated timber frame construction Zaključno delo obravnava možnosti uporabe furnirnega slojnatega lesa iz bukovine (BauBuche LVL) pri načrtovanju sodobnega lesenega stanovanjskega objekta Dom24h. Namen dela je bil ugotoviti, kakšen vpliv ima uporaba visoko trdnostnega bukovega LVL na dimenzioniranje nosilnih elementov, nosilnost konstrukcije, povesne deformacije, porabo materiala ter možnost nadomeščanja jeklenih nosilcev. V okviru raziskave sta bila izdelana in analizirana dva geometrijsko in obtežno enaka statična modela objekta. Prvi model temelji na uporabi konstrukcijskega lesa C24, lepljenega lesa GL24h in jeklenih nosilcev, drugi pa uporablja furnirni slojnati les BauBuche za najbolj obremenjene stropnike in nosilce. Izračuni so bili izvedeni skladno z določili Evrokodov za lesene in jeklene konstrukcije. Rezultati kažejo, da uporaba materiala BauBuche omogoča bistveno zmanjšanje dimenzij prerezov ter porabe lesa pri elementih večjih razponov. Pri nekaterih stropnih poljih se je količina materiala zmanjšala za približno 50 %, hkrati pa je bilo mogoče zmanjšati število nosilnih elementov. Ugotovljeno je bilo tudi, da lahko BauBuche GL75 uspešno nadomesti jeklene profile pri glavnih nosilcih objekta ter zagotovi primerljivo togost in uporabnost konstrukcije. Analiza je pokazala, da pri elementih iz BauBuche nosilnost praviloma ni merodajen kriterij dimenzioniranja, temveč povesi in deformacije. Na podlagi rezultatov lahko zaključimo, da je uporaba bukovega LVL konstrukcijsko najbolj upravičena pri velikih razponih in visoko obremenjenih elementih, kjer omogoča učinkovito optimizacijo konstrukcije ter zmanjšanje potrebe po jeklenih nosilcih. This thesis investigates the application of beech laminated veneer lumber (BauBuche LVL) in the design of a modern timber residential building, Dom24h. The main objective was to evaluate the influence of high-strength beech LVL on structural member design, load-bearing capacity, deflections, material consumption, and the possibility of replacing steel beams. Two geometrically identical structural models of the building were developed and analysed. The first model was based on conventional structural timber C24, glued laminated timber GL24h and steel beams, while the second model used BauBuche LVL for the most heavily loaded floor joists and beams. Structural calculations were performed according to the relevant Eurocode standards for timber and steel structures. The results show that the use of BauBuche significantly improves material efficiency in long-span structural members. In some floor systems, the required timber volume was reduced by up to 50 %, while the number of load-bearing elements was also decreased. Furthermore, BauBuche GL75 was shown to successfully replace steel IPE beams in the primary load-bearing system while maintaining comparable stiffness and serviceability performance. The analysis revealed that the governing design criterion for BauBuche members is generally serviceability, specifically deflections, rather than ultimate load-bearing capacity. The study confirms that beech LVL is particularly beneficial in heavily loaded structural members and long-span applications, where it enables structural optimisation and reduces the need for steel reinforcement within timber buildings. lesene konstrukcije BauBuche furnirni slojnati les (LVL) konstrukcijski les C24 lepljen lameliran les GL24h statična analiza nosilnost konstrukcije povesi optimizacija konstrukcije nosilci velikih razponov timber structures BauBuche laminated veneer lumber (LVL) structural timber C24 glued laminated timber GL24h structural analysis structural load-bearing capacity deflections structural optimisation long-span beams true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-08-20 02:13:12 2026-09-15 13:35:44 2026-09-16 03:11:25 0000-00-00 00:00:00 2026 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 MAG_Medved_Tadej_2026.pdf MAG_Medved_Tadej_2026.pdf 1 2FAB4C3248DD595B7F3E10531EB51089 26c153f011b1114f7cc561ce73afdf0a2e624c87de1f8d5ebaaba64fbcecfc82 ff49d1b0-a18c-11f1-a6e9-00155d0001be https://dk.um.si/Dokument.php?lang=slv&id=210641 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
