The behaviour of composite walls with profiled steel sheetingGallocher, Stewart Craik January 1993 (has links)
During the 1980's the application of composite slabs with profiled steel decking grew rapidly replacing reinforced concrete flooring systems. Reductions in construction time and costs assisted in this rapid shift in building practice away from more traditional methods towards the currently popular "Fastrack" construction. It is therefore a logical extension to investigate the possible use of profiled steel decking as composite walling. This thesis investigates the possible application of double-skin composite walls with a concrete core through experimental and theoretical studies of the behaviour. The experimental investigations focus on a series of four full-scale pilot tests where the performance at the wet concrete stage before curing and the behaviour under a concentric axial lood is studied. Various boundary and end reinforcement details are tried. Analytical equations based on one-dimensional analysis techniques are derived to give linear elastic solutions to the stresses and strains formed in each layer. The critical buckling load is also calculated. Further materially non-linear equations including the P-∆ effect are generated. The profiled steel sheeting is shown to be effective formwork, resisting the lateral pressures developed by the wet concrete. The critical nature of the interface bond behaviour between the steel and concrete faces is shown to be of prime importance in determining the axial capacity of the walls. Local buckling of the steel sheeting is considered of secondary importance being easier to predict and control. The problems associated with the possible design of double-skin composite walls are discussed concluding that the axial capacity at present should be based on the capacity of the concrete alone. Further research directions are also outlined.
