Abstract:This paper presents an inverse analysis approach to obtain material properties of fiber reinforced concrete in terms of Young’s modulus, Poisson’s ratio and tensile stress crack width parameters from the load deflection response of a round panel test. The properties were then used in a nonlinear finite element model to simulate the test of a full scale elevated slab subjected to a point load at mid span of the central slab. The simulation reasonably agreed with the experimental test data measured in the field; the predicted load capacity was higher than the test result by 15.5% and the ascending response was also stiffer than the measurement in the field. An alternative simpler yield line analysis was also used to calculate the material strength from the round panel test and then used to predict the load capacity of the full scale test. The load capacity predicted by the yield line theory was in between the finite element simulation and the experimental result.
