Limitations of plastic bending resistance for composite beams deviated from strain-limitation

Currently, the bending resistance of composite steel and concrete circular beams and beam-columns may be analysed assuming the interaction between the steel shell and concrete core but ignoring the behaviour of the part of the concrete core in tension. Some natural and numerical experiments show that an influence of this part of the concrete core on the total value of bending resistance of a composite member may be rather important. Therefore, this paper pre- sents the method developed for the design of hollow and solid concrete-filled steel tubular beams based on the test data. It takes into account an effect of the part of the concrete core in tension and gives a better agreement with test results than EC4 (EN 1994-1-1 2004). Also, the paper presents the results of carried out analytical, experimental and numerical investigations of the hollow centrifuged and solid concrete-filled steel tubular beams.

Steel Section

According to standards CAN/CSA-S6-88 and OHBDC (1983), a fully plastic stress distribution or a linear stress distribution at first yielding of the steel section should be used to determine the factored bending resistance of a composite section made of a non-compact steel section, depending upon the depth of the compression portion of the web. In this paper, an elastoplastic analysis is presented and is illustrated by an example. Comments on some clauses from the S6 Standard are also presented. Key words: bridges, composite beams, elastoplastic analysis.

Car Park

Abstract In this paper, the bending resistance of three metal-concrete composite beams was compared in real car fires in an open car park. Steel and concrete composite beams are often used for the construction of ceilings in multi-storey car parks. The authors made an attempt to evaluate how the replacement of a non-alloy steel girder with a stainless steel or aluminium alloy girder affects the bending resistance of a composite beam under fire conditions. The analysed beams were not fire-protected. They consisted of a concrete slab and a girder made of: non-alloy (carbon) S235J2 (1.0117) steel, X6CrNiMoTi17- 12-2 (1.4571) stainless steel, and AW-6061 T6 (EN AW-Al Mg1SiCu) aluminium alloy.
