Optimal Design of Composite Floor Systems composed of Cellular Beams via Ant Colony Algorithm

Resumo

The use of composite floor systems has been increasing in recent years, primarily with full-web beams, while other beam topologies, such as cellular beams, remain underutilized. The objective of this study is to propose a formulation for the optimal design of composite floor systems composed of cellular beams. The objective function will analyze the costs and final CO2 emissions of the floor. Technical prescriptions proposed in the literature will serve as constraints, as Brazilian standards lack clear guidelines for the design of cellular beams. To solve the optimization problem, the Ant Colony Algorithm (ACO) will be employed. A comparative analysis with solutions proposed in the literature for floors with solid beams will be conducted to assess the efficiency of the proposed solution for composite floors with cellular beams.
