Experimental studies on behaviour of composite slab with profiled steel sheeting

Abstract

Investigation of the midspan deflection and end slip of the composite slabs is presented in this paper. The deflection of composite slabs depends on the shear stiffness of the connection between profiled sheet and concrete. Results of the experimental investigations of a composite slab with profiled sheeting (Trapezoidal type) and concrete are presented in this paper. Total four specimens were cast and tested to interpret the actual behaviour of the composite slab. Experiments were performed on composite slabs with a trapezoidal type of profiled sheeting of 0.8 mm and 1.2 mm thickness. Two specimens were cast with 0.8 mm profile steel sheet and two specimens with 1.2 mm sheet thickness. In the results of these investigations, load versus displacement and load versus slip behavior was observed. A comparison of experimental values of deflections and end slip revealed that agreement between these values was sufficiently good at all stages of the slab's behaviour.
