20.500.12556/DKUM-87463 Numerical analysis of the racking behaviour of multi-storey timber-framed buildings considering load-bearing function of double-skin façade elements The paper presents an innovative approach in the modelling of multi-storey timber-framed buildings, where double-skin façade elements (DSF) are additionally considered as load-bearing wall elements against a horizontal load impact. The mathematical model with a fictive diagonal element developed for timber-framed wall elements with classical oriented strand boards (OSB) or fibre–plaster sheathing boards (FPB) is upgraded for DSF elements. The diameter of the fictive diagonal is determined with either experimental results or numerically obtained results using the time-consuming FEM model with elastic spring elements, which simulates the bonding line between the timber frame and both glazing panes. In the second part of the study, the numerical analysis of a specially selected three-storey timber-framed building was performed using the developed mathematical model with fictive diagonal elements. Two alternative calculations were performed with the DSF elements as non-resisting and racking-resisting wall elements. It was demonstrated on the selected case that the racking resistance (R) of a building can essentially increase up to 35% if DSF elements are considered as resisting wall elements. As a secondary goal of the study, it is also important to point out that by using DSF elements as racking-resisting elements, the distortion in the first floor essentially decreased. It is demonstrated on the selected numerical example that this torsional influence decreased notably (by almost 18%) when the load-bearing DSF elements were used for seismic excitation in the X direction. Therefore, such an approach can open new perspectives in designing multi-storey timber-framed buildings with a more attractive and dynamic floor plan and structure. sustainability timber structures multi-storey numerical analysis DSF racking resistance trajnostna gradnja les večnadstropne konstrukcije numerična analiza dvoslojne fasade prevleke odpornost proti zbijanju true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/sustainability Članek v reviji 2024-03-19 09:27:00 2024-03-19 09:39:47 2024-04-15 11:54:57 0000-00-00 00:00:00 2023 0 0 Str. 1-18 Št. 8, št. članka 6379 Letn. 15 April 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-03-06 2023-04-06 2023-04-07 694.1:519.6 148574467 10.3390/su15086379 2071-1050 Premrov-2023-Numerical_Analysis_of_the_Racking.pdf Premrov-2023-Numerical_Analysis_of_the_Racking.pdf 1 9B34C1A2154523832B643395EB9B810E b0c050ed0f576c08f08b7e6fa1c299ef9e15b1d7ba74ca3b09dc0b285ec4483c 0b228838-e5cc-11ee-8d81-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177013 https://doi.org/10.3390/su15086379 0 225475dd-e5cc-11ee-8d81-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=177014 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
