To ensure the viability of these shear connectors in practice, it is essential to understand their mechanical behaviour under various loading situations. This paper presents the outcomes of an experimental campaign comprising a series of beam tests conducted under both room and elevated temperature conditions. The results of the tests showed that, during a fire - provided that suitable protection is used for the steel beam -, the shear connectors retain their mechanical contribution and composite action between the steel beam and concrete slab is still active along fire exposure, thereby enhancing the flexural capacity of the beam. The findings from this investigation ensure the structural efficiency of demountable steel-concrete composite beams under both fire and ambient conditions, along with their alignment with the circular economy principles. This study sets the ground to facilitate the practical application of demountable steel-concrete composite beams in the construction sector.The authors gratefully acknowledge the Spanish "Agencia Estatal de Investigacion" for the help provided through the Project FIRSTIMB, carried out with a financial grant with reference TED2021-130580B-I00 funded by MCIN/AEI/10.13039/501100011033 and by the "European Union NextGenerationEU/PRTR".
