Abstract

Recently, deep-deck plates has been widely used in the domestic construction market because it can minimize temporary form works with good constructability and economical advantages. In this study, a newly developed Double Rib Unit Deep-Deck (D-deck) plate which can lead to saving story heights has been introduced, and experiments on a total of four D-deck slabs have been carried out to investigate their flexural performances. In addition, in order to analyze the flexural behavior and strength of the D-deck slab according to the degree of composite, nonlinear finite element analysis (FEA) was performed for three cases – fully composite, partially composite, and non-composite, and the load-deflection relationship for each case was compared with the experimental results. It was found that the D-Deck slab can be considered as a partially composite member with the friction coefficient of 0.2.
