Abstract: 
Beams with circular or polygonal openings have been used for decades in steel construction. Lately, these beams, also called cellular beams, are increasingly required to allow the passage of technical pipes (heating, cooling, electrical, etc.) and thus to limit the floor thickness. In concrete construction, conducting web openings in the structural elements requires complicated passive reinforcement arrangements which are often difficult to implement. In order to compete with cellular steel beams with spans going from 12 to 30 m, the high mechanical properties of UHPFRC may be the solution to replace, partially or totally, the shear and cracking reinforcement. This paper presents the first results of an experimental study on five prestressed UHPFRC beams with circular openings tested at the University of Applied Sciences, Fribourg.
