Abstract
For analysis of mechanical property and bearing mechanism of the composite floor consisting of cold-formed thin-walled steel beams and lightweight aggregate concrete panels, the static load test of a composite floor was presented. The floor specimen is simply supported at the two shorter sides of it and the other two sides free. The equivalent uniform loads are applied to the floor through piling up the load blocks on the supper surface of the floor. The displacements of the floor and strains of specimens were measured and analyzed. It is denoted that the vertical displacements of the floor varied linearly with the load while it is less than 8kN, but the slips of main beam and concrete panel vary nonlinearly during the whole loading process. It was seen that there were not evident cracks in the concrete panels while the applied loads are much larger than the normal loads.
