The purpose of this study is to understand the structural performance of the specimens beam by changing the depth and width of the U-shaped composite beam. To this end, experimental specimens by changing depth and width as compared with a reference specimen were prepared and tested. As a result of this study, growth of the depth has great effect on the structural performance while a width increase has no significant effect on the structural performance of composite beam.
