20.500.12556/DKUM-93767 Enhancing racking stiffness in tall timber buildings using double-skin façades: A numerical investigation The main goal of the paper is to present possible benefits in application of previously developed innovative in-plane load-bearing timber double-skin façade elements (DSF) as additional bracing elements in tall timber buildings. Therefore, a six-storey prefabricated timber structure of a height of 15 m and with a regular floor-plan is analysed by a seismic excitation of ag = 0.225 · g with a strong asymmetrical position of transparent façade elements. Two structural solutions are analysed: a hybrid system combining CLT and Light Timber-Framed walls and a non-hybrid structure made entirely of CLT. In both cases, DSF elements are first considered non-resisting and later as racking-resisting bracing elements. Numerical results show that using racking-resisting DSF elements in a hybrid system (CLT+LTF) achieves a similar increase in overall racking stiffness as a non-hybrid CLT structure with non-resisting DSF. Previous studies highlight hybrid timber systems as the preferred approach due to structural, energy-efficient, and ecological advantages. This finding is significant, offering practical benefits and new design opportunities for modern tall timber buildings with asymmetrical transparent façades, improving both energy efficiency and interior illumination in contemporary prefabricated structures. timber glass double-skin façades racking resistance mathematical modelling tall timber buildings seismic design lesene konstrukcije visoke lesene stavbe les steklo dvoslojne fasade numerična preiskava matematično modeliranje togost potresna odpornost seizmično načrtovanje true false true University of Maribor Faculty of Mechanical Engineering Angleški jezik Slovenski jezik https://apem-journal.org/index.html Članek v reviji 2025-07-18 13:22:04 2025-08-18 07:18:02 2026-03-11 11:25:06 0000-00-00 00:00:00 2025 0 0 str. 116-130 no. 1 Vol. 20 March 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-07-24 2025-03-17 2025-04-29 624.011.1.04 242782211 10.14743/apem2025.1.531 1854-6250 APEM20-1_116-130.pdf APEM20-1_116-130.pdf 1 B954865B68FFF66EC64424483BEDF6F9 1dcf04c4e96b43e09a1f09644623cb7dee276fe18e080181141fd45c7e22e0a6 3ca055d6-63ca-11f0-9d87-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193795 https://apem-journal.org/Archives/2025/VOL20-ISSUE01.html 1 6f854b33-63c9-11f0-9d87-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=193794 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Advances in production engineering & management 0 0 0
