The existing codes of practice propose the live load arrangements in such a way that they result the maximum internal forces in structural analysis. When this rule is utilized for high-rise buildings, a high number of load combinations is required to be applied. Since the use of computers in structural analysis is wide-spread in recent years, an automatic load combination arrangements needs to be developed within a computer environment. Such high number of load combinations and solutions are time consuming and difficult in manual calculations. However, insufficient investigations on this subject have been published, recently.

The primary purpose of this study is faster and more precise calculation of the section forces due to the live load arrangements. For this purpose a genetic algorithm based load arrangement program was developed. The results obtained from the genetic search based method give more precise and rapid results compared to the existing methods.
