NUMERICAL CHARACTERIZATION OF INNOVATIVE DEMOUNTABLE BEAM-COLUMN CONNECTIONS USING LONG BOLTS
Circular design strategies such as adaptivity, detachability, and reusability represent new challenges and increased demands on the future-proof buildings sector. To contribute to the circularity and sustainability of the steel construction sector, an innovative solution of beam-column moment-resisting joints with long bolts and short steel elements (links) is proposed, enabling an extension in the service length of existing steel members. This paper assesses the influencing connection parameters (e.g. bolt preload, bolt length and diameter, end plate thickness, etc.) on the moment (flexural) resistance, stiffness, rotation, ductility, and failure modes of base configurations of these joints.
