A PLATE MODEL FOR COMPOSITE SLAB ANALYSIS

Composite floor decks constructed with profiled steel sheeting acting as formwork and reinforcement to a concrete slab are increasing in popularity. In this paper an elastic folded palte method of analysis has been applied to model their behaviour. The analytical model idealises both the steel sheeting and the concrete as a collection of thin-walled plates and separates the bending and shear action between horizontal and vertical elements. The effects of concrete in tension and slip between the concrete and steel have been included. The method has been used to analyse the results of 32-full-scale slab tests and is found to give good results. © 1990.
