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 ...

The reuse of structural steel elements is an effective strategy for reducing the environmental impact of construction. However, the practical application of reclaimed steel members may be limited by geometric incompatibilities between existing member dimensions and the requirements of new structural systems. The possibility of adjusting the effecti...

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...

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...
