Longitudinal shear failure is the most common failure-type in composite slabs. In this paper, the shear-connection behavior of composite slabs with a particular profiled steel sheeting, so called ACE-DECK, having a depth of 60mm is studied experimentaly. Twenty two pull-out test specimens of different shapes, concrete topping thickness, and different steel sheeting thickness are carried out. It is founded that the shear connection behavior of composite slabs are not affected significantly in the steel sheeting thickness and concrete topping thickness. A new type of profiled steel sheeting is more effective in shear-bond strength that of existing flat-type deck plate, which can offer longitudinal shear strength in composite slope up to $3.6kgf/cm^2$

This paper present a study on the flexural behavior of composite slabs using the flat-type profiled(ACE-DECK) steel deck plate which are developed recently. Forty eight composite slabs with different thickness, span, shear span and deck profile were tested to evaluate the flexural capacity and compared to the existing traperzodial deck profiles (KEM, ALPHA-DECK) According to the experiment results, flat-type profiled steel deck plate indicates more excellent capacity than existing traperzodial deck profiles in strength, stiffness, and ductility. The equation proposed by ASCE code for the effective moment of inertia are more acceptable than the equation proposed by ACI code. Thus, in this paper, test results are summarized by strength, stiffness, and deformation capacity for the specimens.

The purpose of this study is to propose structural technologies on the light-weight composite floor systems in the unit modular and to evaluate structural performance of the composite floor through flexural experiments. The flexural experiments were carried out on total nine specimens(each three type in shape) using steel flat deck and truss deck. From the results of test, all specimens showed the same failure patterns which exhibited deflection at the center of the specimens due to flexural deformation before concrete crushing at the upper of specimens. Also, we know that the proposed floors satisfied in serviceability and would be safe sufficiently. The ratio of experimental yield load by theoretical nominal load was the distribution of 0.86 to 1.27 with an average 1.04. Coefficient of variation in distribution showed good agreement.
