Abstract
Tensile Stress-Strain Relationship for UHPFRC based on notched 3-point-bending tests. Both the tensile strength and the residual tensile strengths of fibre reinforced concrete are generally determined indirectly by flexural tests. For this purpose, a force-deformation curve has to be converted into a tensile stress-strain curve. For ultra-high performance fibre reinforced concrete (UHPFRC) there is currently no regulated conversion procedure due to the lack of valid standards and guidelines in Germany. To analyse the tensile stress-strain behaviour of UHPFRC, notched 3-point-bending tests according DIN EN 14651 were carried out at iBMB, Division of Concrete Construction of the TU Braunschweig. A conversion procedure for UHPFRC based on the Model Code 2010, which regulates normal- and high-strength fibre reinforced concrete, was developed taking into account the test results. The finite element method (FEM) was applied for validation.
