Prediction of Shear Resistance of Headed Studs in Troughs of Profiled Sheeting
Where a composite floor slab is supported on a composite beam of steel and concrete, shear connection is provided by studs in troughs of the sheeting. The resistance of these studs to longitudinal shear depends on over 20 parameters, of which 15 appear in the mechanical models for shear resistance of Johnson and Yuan [1998]. These models have been revised. The mean of over 200 ratios of test/predicted shear resistance is now 1.03. Their mean is higher and their variation is much less than for ratios predicted using the design method of ANSI/AISC 360-05 (2005). Ratios of test to predicted shear resistances to the relevant British standard and the Eurocode have been studied elsewhere. Summaries of these results are given. All the comparisons show that methods that are both accurate and simple will not be found unless the number of variables is reduced by further standardization.
