Abstract
A proposal for a standard test to determine fracture parameters of concrete was recently submitted to ACI committee 446 and to RILEM TC 187-SOC. This paper first summarizes the test procedure and over lights the most important aspects of it. To analyze the reliability of that test, an experimental study was carried out applying this test to four concrete mixes, two for normal strength concrete (NSC) and two for high strength concrete (HSC). The calculations were carried out with special finite elements recently developed by the authors that incorporate the crack behavior as an embedded cohesive crack with limited adaptability. The results show that both the test and the computational method are suitable for HSC as well as for NSC.
