Abstract: A growing number of structural problems associated with excessive vibrations of steel-concrete composite floors due to human rhythmic activities is the main motivation for the development of an analysis methodology supported by design guides and several researches to obtain the dynamic response of a steel-concrete composite floor spanning 40 by 40 m when subjected to human rhythmic dynamic loads. Therefore, this research develops a study based on the use of two different mathematical formulations used for modelling human rhythmic actions (aerobics). Furthermore, it was observed that high levels of annoying vibrations were reached during the aerobic activity.

Abstract: This paper presents the performance of developed firefly algorithm which is formed to be used in the problems where decision variables stem from each other. In this regard, the proposed algorithm so-called “DFAORO” is used to a benchmark multi-reservoir problem in continuous domain. So as to examine the results of DFAORO, linear programing (LP) and standard firefly algorithm (SFA) are applied. Final results based on the value of indicate that DFAORO differs from LP by 0.0015 percent. Whereas SFA is about 37 times worse than DFAORO compared to LP. All in all, it can be asserted that DFAORO has proved more robust and effective.
