In recent years, numerous researchers around the world contributed to the development of ultra high performance concrete (UHPC), and first applications in structural engineering demonstrate the potential of this new building material. Most promising in that respect is the use of ultra high performance fiber reinforced concrete (UHPFRC) in combination with steel reinforcement. For this reason, the deformation behavior of UHPFRC tension chords reinforced with different types of steel has been experimentally investigated. In the present paper an analytical model is presented which enables the calculation of the cracking and deformation behavior of reinforced UHPFRC structural elements. Furthermore, with help of a parametrical study failure modes and minimum reinforcement requirements are studied. The overall aim of this research is to develop reliable procedures for the conception and design of structural members made of UHPFRC. |
