Optimal Design of Composite Cellular Beams with Partial Interaction and its Environmental Impacts

Resumo

This work aims to present the formulation of the optimization problem of composite cellular beams of
steel and concrete considering partial interaction between beam and slab, based on the design restrictions
prescribed in specialized literature adapted to the current Brazilian standardization. Genetic algorithms are used to
solve the optimization problem by finding the combination of geometry of the steel profile, characteristic strength
of the concrete and degree of shear connection that minimize financial cost and CO2 emission. Finally, this
methodology is applied to problems mentioned in literature for comparison and validation purposes.
