Abstract: This article presents the possibility of applying innovative fasteners made of corrugated metal sheet in the dovetail-shape and shot nails to make a steel-concrete composite beam.The beam was built using fasteners made of metal sheet with a thickness of 1.00 mm and 2 or 4 shot nails into single sheet fold.The nails were shot through the sheet into the flange of the steel I-section.The 7.5 m long beam was subjected to a bending test.Based on the experimental studies, a numerical model of the beam was developed in the ADINA System program.The used concrete material model, taking into account the post-cracking and crushing behaviour allowed to locate critical areas of failure.The beam connectors showed sufficient load-bearing capacity and the concrete slab was the weakest component of the composite beam.The beam was damaged as a result of cracking in the slab and, as a consequence, local detachments of the corrugated sheet from the concrete slab.The proposed solution can be used as the fastener for steel-concrete composite structures ceilings of small utility public buildings.
