Özet

In this study, Rao1, Rao2, Rao3, SAMP-Rao1, SAMP-Rao2, SAMP-Rao3, and Ch-SAMP-Rao

algorithms developed using a chaotic switching strategy were used in the optimum designs of single-span

reinforced concrete slab bridge superstructures with minimum CO2 emissions. The main purpose of the study is to

examine the performance of the developed Ch-SAMP-Rao algorithm compared to other Rao algorithm versions.

In the developed chaotic SAMP-Rao algorithm, switching was performed between the search equations used in

the SAMP-Rao1, SAMP-Rao2, and SAMP-Rao3 algorithms with chaotic maps. Thus, it was thought that these

three algorithms, which show different performance in different problems, could show a more stable performance.

For this purpose, a problem suite consisting of two different reinforced concrete slab bridge problems was created

by considering the AASHTO-LRFD Bridge Code. There was a total of 13 design variables in the problem. These

were deck thickness, main rebar diameter in the interior and edge strip, distribution rebar diameter in the interior

and edge strip, shrinkage and temperature rebar diameter, concrete grade, steel rebar grade, main rebar spacing in

the interior and edge strip, distribution rebar spacing in the interior and edge strip, and shrinkage and temperature

rebar spacing. The findings obtained as a result of the independent simulations were evaluated with box plot

graphics and the Friedman test, which is a non-parametric statistical test. The findings showed that the performance

  1. of the proposed Ch-SAMP-RAO algorithm is better than the others.
