MODAL TESTING AND VIBRATION MEASUREMENTS OF A FULL-SCALE CLT FLOOR
Cross-laminated timber (CLT) floors are increasingly used in long-span buildings as a greener alternative to reinforced concrete, steel and their composites. Despite high stiffness, relatively low mass of CLT makes such floors prone to pedestrian-induced vibrations. While these vibrations do not threaten structural integrity and safety, they often ...

ON DED-ARC HYBRID TRANSITIONAL JOINTS IN STRUCTURAL APPLICATIONS
This paper investigates the fatigue performance of a hybrid transitional joint in an I-girder stiffener using DED-Arc AM46 steel from a material and detail perspective. High-cycle fatigue (HCF) tests were performed on machined/polished specimens extracted in horizontal and vertical directions relative to the welding beads. The obtained results were...

COMPARISON AND TUNING OF MACHINE LEARNING MODELS FOR COLUMN WEB PANEL IN TRANSVERSE COMPRESSION
The component method enables efficient design of steel joints by decomposing them into individual components characterized by their resistance and stiffness. This paper presents a machine learning-based approach for resistance prediction of the column web panel in transverse compression, based on a numerical dataset generated using IDEA StatiCa Con...

BEHAVIOUR OF 3D-PRINTED CONCRETE WALLS UNDER LATERAL LOADING: LITERATURE REVIEW
In recent years, 3D concrete printing (3DCP) technology has found growing application in residential construction, from single and two-storey houses to apartment buildings. Nevertheless, the wider application of this technology is limited by the lack of established standards and design codes, the development of which requires a sufficiently large e...

REGRESIONI PREDIKTIVNI MODELI ZA DIMENZIONISANJE VERTIKALNIH SERKLAŽA U ZIDOVIMA UOKVIRENIM SERKLAŽIMA
Trenutno važeći Evropski standardi propisuju minimalne kriterijume za serklaže u zidovima uokvirenim serklažima, dok se zahtevi u pogledu unutrašnjih sila u njima uglavnom eksplicitno ne određuju. U ovom radu predstavljena je metodologija bazirana na podacima iz numeričkih analiza usmerena ka racionalnom dimenzionisanju serklaža prema realni...
