Research of Mechanical Performance of Thin-Walled Steel Lightweight Concrete Composite Floor

Abstract:

For study of mechanical performance and bearing mechanism of the fabricated composite floor consisting of thin-walled steel beams and lightweight aggregate concrete panels, the static load experiment of a composite floor was finished and presented. The specimen is simply supported at the two shorter sides and the other two longer sides free. The equivalent uniform loads are applied to the floor through setting the load blocks on the supper surface of the floor. The vertical displacements and strains of the specimen were measured and analyzed. The experimental results show that the new composite floor has greater bearing capacity and better elasticity. It is concluded that although there is combined action between the main beam and the concrete panel, there is also evident slip between top flange of the main beam and the concrete panel.
