This paper presents a numerical analysis of a material test program investigating the crack opening properties of fibre reinforced concrete (FRC) round determinate panels (RDP). The objective of this research is to set up a modified RDP test method to improve the current ASTM C1550 test method for FRC and fibre reinforced shotcrete (FRS) composite. By this test method, light small-diameter panels are applied and more crack informa-tion can be obtained by a new rotation angle measuring technique. It is shown that this modified test method can be used to effec-tively evaluate the crack opening resistance of FRC. The finite element analysis was then performed to clarify the crack propaga-tions and failure mode of FRC RDP panels. It helps establish a reasonable theoretical method to predict the structural response of RDP, combining with this modified testing technique.
