Abstract:

Ultra high performance fibre reinforced concrete (UHPFRC) is a new construction material that enables the construction of slender and aesthetically appealing structures. First applications in structural engineering demonstrate the potential of this new building material. Most promising in that respect is the use of UHPFRC in combination with steel reinforcement. For this reason, the behaviour of UHPFRC tension chords reinforced with different types of steel has been experimentally investigated. In this paper an analytical model is presented which allows the calculation of the behaviour of reinforced UHPFRC tension chords. Based on a parametrical study failure modes and minimum reinforcement requirements are studied. Considering applications, significant benefits can be achieved with regard to the aesthetics by using filigree trusses. The possibilities are outlined with help of an example girder made of UHPFRC.
