Environmental Impact and Cost Analysis on the Optimum Design of Composite Frame System

Resumo

The objective of the present work is present the optimization problem with a focus on the financial and environmental
impacts of a system formed by a column of steel columnsthat support a floor with beams and compositeslabs of steel and concrete,
steel deck formwork welded on beams, reinforcing steel mesh, crack reinforcement and different concrete compression strength
(fck). The genetic algorithm was used to find the solution to the optimization problem and the objective function is composed of
CO2 emissionsfrom the above-mentioned components. An example has been studied to demonstrate the effectiveness of the
proposed formulation.In this example, the concrete fckwas varied to a value of 50MPa for the analysis andcomparison of emission
values. The results indicated a reduction in CO2 emissions and financial cost.
