Evaluation of the Warping Model for Analysis of Polystyrene Concrete Slabs with Profiled Steel Sheeting
In this article the possibility of applying the warping model offered by V. G. Piskunov, A. V. Goryk and V. N. Cherednikov for analyzing polystyrene concrete slabs with profiled steel sheeting is considered. The adequacy of the offered model was verified by comparing the experimental and calculated deflections of the slab. Test specimens of polystyrene concrete slabs with profiled steel sheeting (PCSPSS) were made for experimental studies and then mechanical properties of the slab components – the polystyrene concrete and the profiled steel sheeting – were determined. Then the behaviour of slabs under a load was studied. The calculation of the warping model of PCSPSS was done at the same time. The obtained results have proved the possibility of applying of the offered warping model for analysis of PCSPSS. It is proposed to use the considered model for further study of the stress-strained state of inhomogeneous slabs.
