Implementation of demountable beams in steel-concrete composite floors enables
structure reuse during several life cycles, consequently leading to savings in material
consumption and reduction of emissions, providing overall ecological benefits.
The behaviour of the innovative demountable beam with a shear connection consisting
of headed studs and bolts is analysed in this paper. The proposed beam is
formed of a steel profile and a steel-concrete composite slab cast in open trough
profiled steel sheeting. Headed studs, welded to the additional steel angles, are
placed in sheeting ribs, whereas bolts are installed between ribs, connecting the
steel angles and profile flange. A numerical FE model of a full-scale steel-concrete
composite beam has been developed to analyse the beam behaviour under service
loads. Experimental results of push-out tests have been used to describe the loadslip
behaviour of headed studs, whereas bolt response has been simulated according
to the expe...rimental investigations of lap joints with preloaded bolts and oversize
holes. The parametric study has been conducted by varying the bolt diameter, grade
and bolt hole size. The results have validated the applicability of the proposed system,
confirming the fulfilment of serviceability limit state requirements.
