Design of circular composite beams with a different concrete core considering the effect of concrete in tension



Presently, the bending resistance of composite steel and concrete circular beams and beam-columns is evaluated supposing the connection amid the steel shell and concrete core but overlooking the behaviour of the part concerning the concrete core in tension.


Some natural and numerical researches reveal that an effect of this part of the concrete core on the total value of bending resistance of a composite member is supposed to be very crucial.


For that reason, this paper explains the process evolved for the design of hollow and solid concrete-filled steel tubular beams on the basis of the test data. It considers an effect of the part of the concrete core in tension and provides an improved agreement with test results than EC4 (EN 1994-1-1 2004).


Also, the paper provides the outcomes of executing analytical, experimental and numerical studies of the hollow centrifuged and solid concrete-filled steel tubular beams.
