The majority of conventional composite beams are of the exposed-type, where steel beams are placed on top of concrete. However, exposed-type composite beams require formwork for concrete and necessitate consideration of local buckling of the steel web during the design process. To overcome these drawbacks, this study aimed to evaluate the performance of filled-type composite beams using U-shaped steel sections filled with concrete. U-shaped composite beams allow the use of steel sections as formwork and provide resistance to local web buckling due to the concrete filling. Moreover, in this study, angle-type shear connectors capable of withstanding concrete side pressure, rather than the typical stud-type shear connectors, were employed. Ultimately, this paper conducted a performance evaluation of U-shaped composite beams and aimed to present a finite element analysis model of composite beams using the ABAQUS program.
