The CONNECT4C project promotes circular construction through the development of adaptable and reusable steel joints that combine structural robustness with the requirements of practical engineering design. The project focuses on innovative moment-resisting joint concepts incorporating components such as “long bolts”, “sliders”, and “hyperpacks”, enabling demountable assemblies and providing geometric flexibility for future structural reuse and reconfiguration. This paper presents the fundamental concepts of the proposed joint system and reports the first experimental results from a broader experimental campaign on a two-sided beam-to-beam joint configuration. The tests investigate the behaviour of the connection in the hyperpack–slider interface and the influence of different slider geometries and bolt arrangements on the global response of the joint.
