Abstract
Currently, steel reuse is only a marginal practice. To facilitate deconstruction and efficient reuse of steel components,
an innovative connection system was proposed. This system adopts a ‘Block Shear Connector (BSC)’ that
allows beam length to be standardised and suitable for a wide range of different sizes of the supporting members
within the same planning grid. This paper presents the experimental and numerical studies of a beam-to-beam
connection using BSCs. The BSC used was made from a standard universal HE / UC section and was bolted to
the beams by using partial depth end plates. The experimental results provided the shear resistance, momentrotation,
failure behaviour, demountability and reusability of the steel components. Further numerical simulation
conducted investigated the effect of some key parameters (steel strength, thickness of BSC web, thickness of
BSC flange, initial bolt stress) on the behaviour of the connections. The results obtained highlighted the
demountability of this innovative bolted connection system and the reusability of structural components.
