Ultra high performance fiber reinforced concrete (UHPFRC) has a compressive strength in the range of 200 MPa as well as improved durability properties compared to normal strength concrete. By the addition of short steel fibers the behavior of UHPFRC in compression and tension is affected in a beneficial way. However, for structural applications conventional reinforcement is still required to obtain ductile failures. Although the mechanical properties of UHPFRC have been widely studied, UHPFRC is quite unexplored in practical applications. Therefore, the deformation behavior of UHPFRC tension chords reinforced with conventional as well as high-strength steel has been experimentally examined. In this paper an analytical model is presented which enables the calculation of the cracking and deformation behavior of reinforced UHPFRC elements in tension. |
