Experimental study of composite steel-concrete column with several fully encased steel profiles subjected to simple bending

Abstract

    The article presents the details of the experimental program dealing with the behavior and the real load bearing capacity of composite steel-concrete beam with several fully encased steel profiles (hybrid steel-concrete beam) subjected to simple bending. Especially identify the bearing capacity while the materials were yielded until failure. Contents of the paper consist: descriptions of the specimens and their fabrication, material property information and test layout and procedure details. These test specimens were prepared and tested at the Structures Laboratory of the INSA Rennes, France (National Institute of Applied Sciences of Rennes). The experimental beam full scaled the sectional geometry size and length, as well as the layout of reinforcing steel. The measurement data obtained will be processed and analyzed in the detail to point out the mechanical force transmission behavior inside the reinforced concrete beam under simple bending until failure.
