Experimental evaluation of effective width in steel-concrete composite beams / Amadio, C; Fedrigo, C; Fragiacomo, Massimo; Macorini, L.. - In: JOURNAL OF CONSTRUCTIONAL STEEL RESEARCH. - ISSN 0143-974X. - 60:2(2004), pp. 199-220. [10.1016/j.jcsr.2003.08.007]
abstract:
The paper deals with the evaluation of effective width for elastic and plastic analysis of steel–concrete composite beams. The study is performed through experimental tests performed
at the University of Trieste on four specimens. Both cases of sagging and hogging
bending moments are investigated, as well as the influence of the beam-to-column joint. It is shown that for all specimens the effective width increases with the load, approaching the
width of the whole slab near the collapse. The presence of a beam-to-column joint does not affect this result. The comparison with the Eurocode 4 formulation demonstrates that such approach is adequate for elastic analyses, whereas it may be too restrictive for plastic analyses. A simple modification of the Eurocode 4 proposal is therefore presented for collapse
analyses of composite beams under hogging bending moment.
