Description
Summary:An experimental investigation on the behavior and strength of full-scale one-way single span composite slabs with ribbed decking is presented. Different aspects were studied, including different steel deck thickness, total slab height, as well as shear span length. The effect of connectors (stud bolt type) on the end anchorage was also investigated. Normal procedures for batching and mixing the concrete were used. Throughout the monotonic loading tests, midspan deflections, end slips and strains in steel decking were measured. The test results indicate expressively the better performance in the slabs built with the stud bolt connectors. The behaviour and strength of the composite slabs are also compared to the partial interaction design method specified in the Eurocode 4. This comparison shows that some improvements can be made in the design equations, and a modification is proposed herein.
