Behaviour of headed studs in composite beams: full-size tests

Abstract

This paper summarizes the results of tests conducted on four full-size composite beams and two full-size push-off specimens which are companions of the first two beams. In these specimens, the ribbed metal deck was placed perpendicular to the beam span. Concrete pull-out was the principal mode of failure. The ultimate horizontal shear loads observed in the push-off specimens agreed reasonably well with those predicted using an empirical equation proposed by the authors. The predicted values of flexural capacity, calculated indirectly using the same equation, were in good agreement with those observed in the four beam specimens. Key words: composite beam, headed shear stud, stud shear capacity, stud pull-out failure, full-size tests, perpendicular ribbed metal deck.
