OPTIMIZED DESIGN OF HOLLOW CORE STEEL BEAMS

This paper proposes a formulation for the optimized design of steel hollow core beams using the equations developed by several authors. The validation of the developed computer program was performed from the comparison with the results obtained through manually solved examples since the Brazilian standard does not define the design parameters for honeycomb beams. The program was developed in the Matlab platform and to solve the optimization problems the internal algorithms of Matlab were used such as interior points quadratic programming and genetic algorithms. Initial examples point out that the sizing can be improved and in the case of profile manufacturing a new cutting line can be defined.
