Discrete Representation of Steel–Concrete Composite Beams under Bending

Abstract For reinforced concrete structures, whose nomenclature and field of application are constantly expanding under modern conditions, the reduction of material consumption in most cases is achieved by decreasing the use of materials such as cement, crushed stone, reinforcing and rolled steel, as well as by searching for new efficient structural forms and design solutions. One of the ways to address this problem is the search for and development of new efficient structural systems, along with the improvement and advancement of calculation methods. The use of steel–concrete composite beam structures in modern construction is one of the approaches to finding efficient designs, since they are more economical in terms of steel consumption - by 5–20% compared to steel structures. They also allow for a reduction in the structural depth and enable more efficient utilization of the physical and mechanical properties of the materials (concrete and reinforcement), which is particularly important in the construction of buildings and structures, while maintaining their load-bearing capacity and deformability.
