Ponts et charpentes Résumé : A finite-element model (FEM) is developed to predict the load-displacement behavior of a composite wood-concrete floor/deck system under short-term loading. The interlayer connection was modeled with link elements dedicated for connection modeling. Results of past tests of two full-scale layered floor/deck specimens are employed to confirm the FEM model. The specimen had a layer of solid sawn lumber overlaid by concrete and interconnected to it with a pattern of notched shear key/anchor details. The FEM results agreed closely with the measured deflection data for the loadings considered. The efficiency of composite behavior achieved by each of those specimens is quantified by a conventional and three improved approaches based on the computer modeling and measured test results. The new approaches better capture the overall efficiency of the entire floor/deck.
