Abstract [en]

This paper discusses deficiencies in the design methods presented in Eurocode 4 and the method proposed for possible application in Australian codes. An attempt has been made to formulate a new design method which is consistent with Eurocode's safety concept and as close as possible to the existing design model for partial connection used in Eurocode 4. The new procedure has three corner stones. An experimental program is used to establish material and interface characteristics. So called small scale tests (push test, tension-push test, and friction test) are used as the basis for the interface models used in FE calculations and to provide statistical characteristics of basic variables. A finite element parametric study of a simply supported slab is used to predict the distribution of resistance. The procedure presented in Annex Z of Eurocode 3 is used to evaluate the partial safety factor for resistance. A simple to use design formula has been derived for the longitudinal shear failure and the flexural failure of simply supported slabs.
