Abstract

The behavior of shear connections in
 composite beam construction has been
 determined by a comprehensive experimental
 examination conducted in compliance with
 EC4-1-1Annex B.2. In order to illustrate the
 steel-concrete
 composite
 ultimate
 strength
 behavior
 construction's
 from the
 component level to the structural level, six
 push-out experiments were published. Push
out tests were used to examine the specimens
 while
 varying
 constructive
 parameters.
 Longitudinal and transverse steel sheeting
 types and positions were varied for headed
 stud
 connectors
 with
 d=19mm and
 hsc=100mm. Additionally, there were
 variations in the number of shear connections
 in the cross section (1 or 2) and the welding
 process, both via deck welding and with holes.
 We re-adopted concrete with grade C25/30,
 which is the commonly used grade, and
 reinforcing with a low percentage. When the
 results of load capacity were compared to the
 intended load capacity as per EC4-1-1 (6.6.3
 and 6.6.4), there were sometimes notable
 variances.
